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