PSK Demodulator with Delay Line for the PCM-TDMA System

In the pulse-code modulation-time-division-multipleaccess (PCM-TDMA) system for the next global satellite communications, minimization of synchronization bits in each burst is desirable to improve the traffic efficiency. A new phaseshift keyed (PSK) demodulating system with a delay line is proposed to meet the previous requirement, and the design of its scheme and its experimental performance are described. The difference of the error rate performance between theoretical and experimental values was about 0.8 dB, and even in the worst case the error rate of 10
^-4
was assured for an input
E/N_{0}
of 10.5 dB.
