摘要

It has been shown that quasi orthogonal space time block codes (QOSTBC) can achieve high transmission rate with partial diversity. Constellation rotational QOSTBC can achieve full diversity. In this paper, we present a constellation rotational QOSTBC concatenates Reed-Solomon (RS) error correction code structure. At the receiver, pairwise detection and error correction are first implemented. The decoded data are regrouped. Parallel interference cancellation (PIC) and dual orthogonal space time block code (OSTBC) decoding are deployed to the regrouped data. The dual OSTBC decoding can obtain better error performance than constellation rotational QOSTBC. The pure concatenated scheme is shown to have higher diversity order and have better error performance at high signal-to-noise ratio (SNR) scenario than both QOSTBC and OSTBC schemes. The PIC and dual OSTBC decoding algorithm can further obtain approximate 1.0 dB gains than pure concatenated scheme at 10−6 bit error probability (BEP). The BEP performance of the proposed algorithm is very close to that of dual OSTBC scheme with perfect interference cancellation.
