This study discussed the decoding mechanism of block product turbo code (BPTC) (196,96) and analyzed 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 system is based on the Analog Device DSP platform, the C code is used to simulate BPSK modulation and demodulation module, AWGN channel module, BPTC (196,96) coding module to construct a wireless communication system, so as to observe its coding efficiency, and compare its complexity and coding gain with one-dimension Hamming code (15,11). This study also discussed the physical mechanism of decoding difference between Hamming code and BPTC. When the C code system program is constructed, the system program should be optimized and realized on the DSP platform, fast verification and similar functions to software defined radio (SDR) can be realized by replacing modules, such as modulation modules, channel modules and coding modules.
