Abstract
This work reduces the synchronization complexity by using a linear phase approximation to the phase of shaped-offset quadrature phase-shift keying, telemetry group version (SOQPSK-TG) signal. We also use the pulse truncation (PT) method to simplify the phase state. The modulator and coherent demodulator are implemented on the Field-Programmable Gate Array (FPGA). The bit error rate (BER) performance of the proposed method is obtained, which is close to the theoretical optimum performance.
