Abstract

In this paper the performance of the boosted space-time diversity scheme is examined for a transmission over frequency-selective Rayleigh fading channel. The simulation scenario is similar to that of 802.11n Wireless Local Area Network (WLAN) specification. Two interleaver designs (ideal and pragmatic) are considered. Moreover, a few methods for early stopping of iterative decoding are developed to reduce the computational payload of the receiver routine. It is shown that a reasonable performance gain can be achieved by the boosted system in comparison with the 2x2 diversity scheme provided by the 802.11n specification.
