Abstract

In high-speed data communication system,we often use differential encoding and decoding to reduce system complexity.Based on the introduction of the coding principles of unitary space-time modulation,we give the hardware codec programs and flow chart,then implement the codec by C and assembly language on the basis of TMS3205416 DSP.The RTDX debugging result shows that bit error rate computed by DSP is similar to that of the MATLAB′s,verifying that codec in the DSP environment meets the requirements of practical application.And the proposed simplified algorithm can reduce the time of DSP decoding.
