I'm trying to understand the different modulation techniques for the satellite communication
Hello Mardi, digital modulation techniques are presented in books such as Communication Systems of Haykin or Carlson, both text are very good. I think is possible to generate the transceiver using your own algorithms based-DSP. For satellite communications a typical book is from Bruce Elbert o Maral. Take a look on lybrary genesis LibGen to find it out. Good luck! Eduardo
Dear Mardi,
The different digital modulation techniques including the binary phase shift keying can be implemented using digital signal processors. The digital signal processor calcualtes the the required wave forms. In case of BPSK there are two possible implementations:
a base band implementation where logic one is represented by + V and the logic zero is represented by -V , where V is any suitable scalar, and band pass representation where logic 1 is represented by V cos wct and the logic 0 is represented by - V cos wct.
Normally the base band implementation is the common method for DSP to save the computation and reduce the power consumption. If is necessary to implement BFSK in band pass form, it is advisable to select as low as possible carrier frequency wc.
