A Systematic Design of Space-Time Block Codes Achieving Full-Diversity with Partial Interference Cancellation Group Decoding

A partial interference cancellation (PIC) group decoding based space-time block code (STBC) design criterion was recently proposed by Guo and Xia, where the decoding complexity and the code rate trade-off is dealt when the full diversity is achieved. In this paper, we propose a systematic design of STBC that satisfy the criterion, i.e., achieve full diversity with the PIC group decoding for any number of transmit antennas. Moreover, the proposed full-diversity STBC can achieve a rate of 2 symbols per channel use for any number of transmit antennas when the code length is large. Some design examples are given. Simulation results show that the newly proposed STBC can obtain full diversity over flat Rayleigh fading channels and outperform some existing codes given the same bandwidth efficiency.
