Throughput and Coverage of WLANs Employing STBC Under Different Channel Conditions

Overview HIPERLAN/2 and 802.11a/g WLANs employ Coded Orthogonal Frequency Division Multiplexing (COFDM) to provide data rates of up to 54 Mbps in a 20MHz bandwidth. In this paper, Space-Time Block Coding (STBC) techniques are considered as a means of enhancing the performance of COFDM WLANs. Packet Error Rate (PER) and throughput performance results are presented under different channel conditions. A WLAN physical layer simulator employing STBC and a propagation modelling tool are combined in order to evaluate the coverage and throughput of hot spot WLANs employing STBC for the 2x2 and 4x4 MIMO cases.
