Chapter 062 Analysis
The next morning, Zuo Cheng was the first to arrive at the company.
He barely slept last night. Lin Jianhua's words kept echoing in his mind, like a thorn, making him restless. But more important than those words was the information he got from Chen Ming: the fatal flaw in beamforming algorithm V3.2.
Zuo Cheng sat in the conference room, a stack of white papers spread out in front of him. He needed to turn this deficiency into a technological advantage for 402.
He closed his eyes and brought up the system interface in his mind.

A cool sensation washed over him, and Zuo Cheng felt his thoughts become exceptionally clear. The system presented the complete mathematical model of the beamforming algorithm, with every parameter and every formula clearly visible.
He started writing and drawing on paper.
The core of the algorithm is an optimization problem, aiming to maximize signal strength under a given power constraint. When the number of satellites is small, this problem can be solved efficiently using convex optimization methods. However, when the number of satellites exceeds one hundred, the dimensionality of the problem increases dramatically, and the solution time grows exponentially.
Why does Huaxin's solution have this flaw?
Because they use a centralized architecture. All satellite signals are aggregated to a central node for unified processing. The advantage of this is simple control, but the cost is extremely high computational complexity.
Zuo Cheng paused, his pen poised.
To solve this problem, the architecture needs to be changed. It needs to shift from a centralized to a distributed approach, distributing computing tasks across various satellites and then coordinating them using iterative algorithms.
He wrote four large characters on the paper: Distributed Collaboration.
This is a technological approach that only matured in the late 2020s of my previous life, making it five or six years more advanced than it is now. If 402 could be implemented now, it would be a huge technological advantage.
Zuo Cheng continued his derivation. Distributed architecture needs to solve three core problems: information synchronization between nodes, load balancing of task allocation, and guaranteeing the convergence of iterative algorithms.
Information synchronization can be achieved using the gossip protocol, where each node only needs to exchange information with its neighbors. Load balancing can be achieved using consistent hashing, which distributes tasks evenly across all nodes.
Zuo Cheng drew a flowchart on paper. The central node is only responsible for coordination and does not process specific data. Each satellite node independently calculates its local beamforming parameters, and then exchanges information with its neighbors through the gossip protocol. After several iterations, it can reach the global optimum.
He calculated the computational complexity. A centralized architecture is O to the cube, while a distributed architecture is O to the linear. This means that with the same hardware resources, a distributed architecture can support more than ten times the number of satellites.
Zuo Cheng's eyes lit up.
This is the breakthrough. No matter how advanced Huaxin's technical solution is, it cannot change the inherent limitations of a centralized architecture. 402, on the other hand, can be countered with a distributed architecture, achieving a significant advantage.
He spent two hours clarifying the entire technical framework. By the time he finished writing the last stroke, the blank paper was filled with formulas and flowcharts.
[Technical analysis concluded]
[Result: Distributed Cooperative Beamforming Scheme]
[Efficiency Improvement: ×1.2]
The system notification brought Zuo Cheng back to his senses. He looked at the results in front of him, a slight smile playing on his lips.
This is the power of technical analysis. A problem that would normally require a team to study for weeks, he solved by himself in just two hours.
At 9:00 AM sharp, the others arrived at the company one after another. Zuo Cheng called Zhang Lei, Chen Hao, Liu Wei, and Fang Ze into the conference room.
"Starting today, we'll enter the third phase of our technical research for the Sky Dome project." Zuo Cheng spread out the results of last night's work on the table. "This is my preliminary design for the integrated space-ground solution."
Chen Hao picked up the white paper, his eyes widening in disbelief.
"A distributed collaborative architecture?" He adjusted his glasses. "That's a novel idea."
"It's not just new," Zuo Cheng said, pointing to a formula on the diagram. "With this architecture, we can support a network of over five hundred satellites, with response latency controlled to within ten milliseconds."
"Five hundred?" Zhang Lei gasped. "Huaxin's plan is capped at two hundred, right?"
"Their solution has a flaw," Zuo Cheng said calmly. "When the number of satellites exceeds one hundred, the algorithm's complexity increases exponentially."
How did you know?
Zuo Cheng paused. Of course he knew, because he had copied Huaxin's core algorithm. But he couldn't say such a thing.
"I've analyzed CEFC's technology roadmap over the past few years," Zuo Cheng said without changing his expression. "Their beamforming algorithm is modified from military radar technology, which inherently has this limitation."
Chen Hao nodded thoughtfully. Zuo Cheng's explanation made sense; everyone in the industry knew that Huaxin's technological foundation came from the military industry.
"Distributed collaboration must be quite difficult to implement, right?" Fang Ze frowned. "Communication delays between satellites and clock synchronization are tough challenges."
"That's right," Zuo Cheng admitted, "but the direction is right. As long as the direction is right, success is only a matter of time."
"How should we divide the work?" Liu Wei asked.
"Chen Hao is in charge of the distributed algorithm, Fang Ze is in charge of hardware adaptation, Liu Wei is in charge of testing, and Zhang Lei coordinates the progress," Zuo Cheng said. "I'm in charge of the overall architecture."
"Hardware adaptation is a huge undertaking, and the satellite has limited computing resources," Fang Ze said.
"Using our edge computing chips, we can offload some computing tasks to the terminal," Zuo Cheng said.
Zhang Lei wrote something in his notebook: "Do we need to add more people?"
"Not for now. Expand it after the prototype passes verification."
"What about time?"
"We'll complete prototype verification within two weeks and deliver a complete solution within a month," Zuo Cheng said. "The tender briefing will be in forty days; we need to allow enough time for optimization."
After the meeting, Zuo Cheng remained alone in the conference room. He brought up the system interface again to check the task progress.
Main Quest Chain: Celestial Overlord
Current stage: Stage 1/?
Current goal: Complete the technical solution design.
Current progress: 15%
Time remaining: 88 days
88 days. Zuo Cheng calculated in his mind. It seemed like plenty of time, but when you factor in prototype verification, test optimization, and documentation writing, the time was actually quite tight.
Furthermore, there are hidden parts in the quest chain, so it's unclear what challenges lie ahead.
Zuo Cheng stood up and walked to the window. Summer had arrived in Hangzhou, and the leaves of the plane trees outside the window were a vibrant green.
In his previous life, he worked at Huaxin for twelve years, only to be ousted in the end. In this life, he will defeat Huaxin and Lin Jianhua on the same battlefield.
The phone rang. Zuo Cheng took it out and saw that it was a message from Yu Ying.
"Are you free tonight? My dad wants to see you."
Zuo Cheng was taken aback. Yu Ying's father?
He replied quickly: "I'm free, what time?"
"Dinner at home at seven o'clock."
Zuo Cheng stared at his phone screen, his heart suddenly skipping a few beats.
He took a deep breath and closed the system interface.
Work is important, but I also need to prepare for the meeting tonight.
