Abstract :
Optimization of satellite repeater parameters with transistor power amplifiers is carried out as per the criterion of a minimum of an error of demodulation for a case of transmission through a communication line of the digital information great volume at the restricted strip of operating frequencies (4 %) relative frequencies of carrying frequency and when using Comtech CDM-700 modem on the Earth. The sender is installed on a HEO space vehicle. Dependences of probability of bit error rate for QPSK and 8PSK signals and various values of path attenuation are obtained.
