EBE Chapter 644 not only exceeds, but also has additional gains!
Chapter 644 not only exceeds, but also has additional gains!
The test workshop was extremely quiet, with only the regular beeping of equipment and the sound of everyone's breathing.
Xie Kang had a thoughtful expression on his face.
"When the ratio of collision frequency to plasma frequency is less than 0.3, is there a negative correlation between the standing wave of the antenna and the attenuation of the radio wave in the plasma?"
He had read the information files there, but he didn't have much impression of such detailed aspects.
Xie Kang hurried to look for the information.
Not long after.
He found the information and took a closer look!
As Li Yang said, there is indeed record of this experimental data.
"That's true. Mr. Li, you have a really good memory."
“It’s just…what specific problems can we solve using this data?”
Xie Kang asked doubtfully.
Li Yang took the information from him and spoke with a smile.
"Professor Xie, this is not about solving a specific problem, but about being able to completely and perfectly resolve the blackout phenomenon!"
Xie Kang looked at him in surprise.
The researchers present also stared at Li Yang with an expression of disbelief.
Such an inconspicuous feature can completely solve the blackout problem?
Where does this saying come from?
Without waiting for them to ask the questions in their minds, Li Yang took the initiative to explain.
"We can use the negative correlation between the physical properties of the two to predict the channel capacity fading caused by the plasma sheath by detecting the standing wave changes at the transmitting antenna port."
"Next, the transmission rate is automatically adjusted to adapt to channel changes, and data priority and buffering mechanisms are introduced to finally realize the adaptive communication mechanism."
He briefly explained the principle. Otherwise, if he really wanted to explain it in detail, it would take at least half a day to explain it clearly.
Li Yang also believed that they were experienced researchers and should be able to understand the principles behind it quickly.
Just as he imagined, Xie Kang thought about it for a while and then understood.
He slapped his thigh and his expression immediately became excited.
"Brilliant! Really clever!"
"Since the transmitter cannot directly obtain feedback information from the channel, we add a medium between the two."
"Through the changes in this medium, we can indirectly and accurately predict the capacity fading caused by the plasma sheath."
Xie Kang was very excited.
The method proposed by Li Yang is not only simpler but also lower cost.
Moreover, the difficulty of the experiment is greatly reduced.
After Xie Kang's guidance, the researchers quickly understood the meaning.
The way they looked at Li Yang showed even more respect and admiration.
"Engineer Li is really amazing. He can even come up with a method like this."
"Professor Xie had shown us this document before, and even explained and analyzed it to us, but no one discovered the mystery behind it!"
"So, if there are no problems with the test, the solution proposed by Engineer Li will be able to completely solve the black barrier problem, right?"
"nature!"
The researchers were immediately excited.
They worked for several years to solve this problem, but there was no progress.
If Li Yang's method can solve the problem, then this project can finally come to a successful conclusion.
Their job then is to continuously improve and upgrade this method.
At the same time, on this basis, more methods have been derived, which will make it easier to solve the black barrier problem in the future, with multiple methods used in parallel.
Xie Kang also thought of this, took a deep breath, and asked.
"Engineer Li, let's work together to come up with the experimental plan as soon as possible. Let's hurry up and start the experiment?"
Li Yang nodded in agreement.
He also hopes to conduct experiments earlier to verify whether this method is feasible.
Xie Kang said.
"You proposed the method. I guess you already have a complete experimental plan."
"Engineer Li, you will be fully responsible for the next experiment."
"All researchers, including me, will accept your orders!"
Hearing his words, the researchers nodded without hesitation and looked at him expectantly.
Li Yang wanted to refuse, but seeing Xie Kang's firm attitude, the researchers also looked expectant.
After thinking about it, I agreed.
"Row!"
"Since Professor Xie believes in me and everyone trusts me, it would be fussy if I refused."
"Let's not waste time talking any more. I will assign tasks to you all..."
In a few minutes, Li Yang regrouped the researchers and assigned corresponding tasks to each group.
The next night.
After all preparations were ready, Li Yang led all the researchers of the entire black barrier project to start the experiment.
"here we go……"
This simple sentence aroused the nervousness of all the researchers present.
In the past, they often did not have much patience for such boring, tedious and lengthy experiments.
but now.
If possible, they were reluctant to even blink in order not to miss the subtle changes during the experiment.
Time passed by minute by minute, and it came to the most critical moment.
Li Yang said in a deep voice.
"Prepare!"
"The plasma is about to cover the antenna!"
Boom!
Everyone's hearts seemed to ring as if a bell was ringing. They suddenly became nervous and their heartbeats accelerated instantly.
His eyes were fixed on the instrument, observing the changes in the numerical values on the instrument.
soon.
As the plasma slowly covered the antenna and completely covered it, the values on the instrument changed.
"Yes, yes, the standing wave at the transmitting antenna port has changed!"
One of the researchers exclaimed, which immediately made the other researchers excited and they all looked over.
can be seen.
The instrument that detects the standing wave changes at the transmitting antenna port in real time showed value jumps, sometimes 1.5mbps and sometimes 325bps.
When Li Yang saw this, his face showed no hurry.
"It's not stable yet, wait a little longer..."
really.
After he finished speaking, the curve that was jumping randomly just now gradually tended to a stable range, and the communication rate began to jump steadily between 4mbps and 250bps.
"Stabilized!"
"Calculate the gain in this numerical range immediately!"
Li Yang ordered.
A group that had been waiting for a long time immediately began to calculate the gain as quickly as possible according to Li Yang's request.
After a few minutes, the team members' eyes turned red and their pupils flickered.
See this.
Li Yang vaguely knew the answer, but still asked.
"How is it? Is the gain above 0?"
He tried his best to suppress the tension in his heart and keep himself calm.
This was the first time since the awakening of the system that he had such a tense moment while working on research and development.
The most fundamental reason is that Li Yang did not use the system to conduct this research. It was entirely the result of his own efforts.
Success or failure means a lot to him!
Although Xie Kang didn't show any change on the surface, his heart was actually beating very fast.
Not to mention the researchers, everyone clenched their hands, their hearts aching.
The team member in charge of the calculation nodded heavily and answered with a trembling voice.
"exceeded!"
"Not only does it exceed that, but it also has an extra 40db of gain!!!"
