Abstract
SOQPSK-TG, which is composed of a precoder and a CPM modulator, adopts a differential precoder method with a differential encoder added to the transmitter as a telemetry standard to simplify the receiver structure. In this paper, we evaluated the effect of the differential encoder on receiver performance at low Eb/No. According to the results of computer simulation, the Eb/No performance in the AWGN channel without the differential encoder is about 2dB better when the BER is 10-1 and about 1dB when the BER is 10-2.
