| Abstract: | A demod-remod coherent tracking loop for QPSK and SQPSK is described and analyzed in [1]. Those results are used to obtain the power spectral density of the equivalent noise of the tracking loop and the probability density function of the steady-state phase error, The effects of the IF and arm filters on the statistics of the noise and QPSK signal are developed. The results of performance computations are presented. |
