Abstract

As a kind of modulation with high degree of both power and bandwidth efficiency, Filtered QPSK (FQPSK) has been widely applied in the satellite and deep space communication. This paper first investigates the Maximum-A-Posteriori-Probability (MAP) demodulation of FQPSK-B. Then a serially concatenated system of FQPSK and LDPC codes is built, which gives both the advantages of LDPC codes and FQPSK and can easily be considered to save the power and spectral utilization ratio of the system. We demonstrate that the new concatenated system can achieve high power and spectral efficiency through extensive analysis and simulation.
