- Abstract
- This study discussed the decoding mechanism of block product turbo code (BPTC) (196,96) and simulated its efficiency, used the Hamming (15,11) and Hamming (13,9) block channel code combinations and block interleaving to construct a BPSK modulation and BPTC (196,96) coding system in the concept of feedback encoding in turbo code. The decoding mechanism was meticulously described to explain the advantage of this turbo feedback structure. This study also analyzed and simulated special combination of MSK modulation with Golay (20, 8) channel code. Golay (20,8) decoding correction capability was comprehensively discussed. The simulation results indicate MSK Golay (20,8) is less robust than BPSK Golay (20,8) for 2.8dB against noise, but BPSK BPTC (196, 96) is 3dB more robust than MSK Golay (20, 8) and it is also a better choice than BPSK Golay (20, 8), if signal Eb/N0 is stronger than 5dB. Whenever the C code system program is constructed, the system program should be optimized and realized on the DSP platform. Both MSK Golay and BPSK BPTC C program optimization efficiency statistics are analyzed. The implementation can be applied to the wireless communication system of SDR concept, so that different modulation and encoding modes can adjust parameters in firmware directly according to different system specification requirements.
