A plan for a 600 Mbps data rate with 20 m of propagation distance has been achieved in multiple-input multiple-output (MIMO) wireless LAN (WLAN) system by using a group layered space-time (GLST) algorithm. We report our design of preamble sequences that use a genetic algorithm (GA) for these WLAN systems. The design optimizes both the low peak to average power ratio (PAPR) and produces better autocorrelation...
Group layered space-time codes can attain a better tradeoff between data rate and diversity gain. In this paper, we propose two generalized detection algorithms for GLST. Firstly, we present a non-ordering linear detection with an extended Gaussian elimination algorithm. Then an ordered successive detection algorithm is derived. These algorithms can reduce computational complexity, as low as O(Nt2...
