A new space-time diversity scheme for WLAN systems

This paper focuses on the applicability of Bit-Interleaved Space-Time Coded Modulation with Iterative Decoding (BI-STCM-ID) to Wireless Local Area Networks (WLAN). A new intuitive space-time diversity scheme, which ensures a low error rate for small signal-to-noise ratios (SNR) and good asymptotic performance, is provided. The presented technique can ensure compatibility with today’s WLAN specifications. The EXtrinsic Information Transfer Chart (EXIT) and the bit error rate (BER) simulations confirm its usefulness.
