If your OFDM system is adaptive, you may have to continuously calculate total bit rate. Just take each subcarrier, and multiply the bit packing per symbol times the symbol rate, and add them all together. If this bit packing changes on a subcarrier, due to noise, for example, you have to...
I think the most reliable way to do this with a sampled or clocked signal is to use a PLL up upshift your clock by 4x, then use the upshifting clock to clock a 3 bit shift register to provide a 3/4 bit delay of the signal. If this is an analog signal, you will need to use an analog shift...
My colleague is actually working on the project. I was a reviewer.
He has a track record for success in the field of Electromagnetics, but not communications. I have a track record in communications, with over a dozen patents in the field of communications, and over 40 patents total.
His...
I can give some information, but it would compromise my company to give too much.
We have up to 1000 linear communication links, each one with losses averaging 20 dB or so, but which could be more (up to double) under some circumstances. Currently, PPM is used to minimize power. The repeaters...
I think in this case it is more a matter of not wanting to reengineer the protocol, rather than wanting long term job security. I think he honestly believes that the 1000 non-regenerating repeaters will actually work. He measured the noise and distortion from a few prototypes in a lab...
I am having a debate with a colleague. He is engineering a system that uses 1000 non-regenerating repeaters. I am try to explain to him why this approach has a very high risk of failure, and why he should use regenerating repeaters instead. The protocol he wants to use does not lend itself to...
