Channel Distortion Effects on a BPSK DS/SS and a QPSK DS/SS Signal Demodulation

  • 발행 : 1988.08.01

초록

The degradation due to channel distortion in a quadrature modulation system from the ideal constant values over the bandwidth of a direct sequence spread spectrum signal are considered. Through using series expansion for the channel gain and phase response, the degradation in the correlator output at the receiver is found as a function of the parameters involved , including phase error, delay error, linear gin variation, quadratic gain variation, and quadratic phase variation.
