Abstract

Comparing with orthogonal space time block code (OSTBC), quasi orthogonal space time block code (QOSTBC) can achieve high transmission rate with partial diversity. In this paper, we present a QOSTBC concatenated 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) maximum likelihood decoding are deployed to the regrouped data. 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 more than 1.3 dB gains than the pure concatenated scheme at 10^-6 bit error probability.
