Abstract

Serially concatenated continuous phase modulation (SCCPM) combines serially concatenated convolutional coding (SCCC) with continuous phase modulation (CPM). Continuous phase encoder which is decomposed from CPM is used as a convolutional coder, and iterative decoding based on log-MAP (maximum a posteriori probability) algorithm is used in decoding, which bring the system good power efficiency and frequency efficiency, 3.0 dB gain at least. In [1] the effects of different parameters on SCCPM system are presented. In [2] we present a joint parameters query. When a channel quality value is given, optimal joint parameters related will be used in the system to get minimum bit error rate (BER), which can bring system an extra 0.5-1.0 dB gain. The encoder and decoder of SCCPM system is implemented on DSP-TMS320C6416 for its high-speed processing despite the complexity of iterative decoding.
