In this paper the asymptotic performance of a new intuitive space-time diversity scheme is analyzed. So called boosted scheme is compatible with today’s WLAN specifications with regard to convolutional coding and bit labelling, and minimizes the number of decoding iterations, required to obtain a reasonable Bit Error Rate. Good properties of the proposed scheme are proved by high asymptotic coding gain and advantageous distance spectrum. A simulation experiment is run to investigate the system performance in terms of poor channel state. The boosted scheme is compared with its ancestor – Bit-Interleaved Space-Time Coded Modulation with Iterative Decoding (BI-STCM-ID).
