Novel 2-4 PSK differential demodulator for satellite broadcast receivers using SAW technology
Abstract
A novel 2-4 PSK differential demodulator based on a three-port SAW delay line is described. A method for optimizing the performance by tuning the carrier frequency using the dc output of the demodulator is outlined. The optimum performance of the demodulator was within 0.4 dB of theory for a bit-error ratio of 0.001.
