Abstract

In this paper, an enhanced system for video streaming over wireless LANs at 5GHz (IEEE802.11a/g and Hiperlan/2) is presented. The proposed system employs Space Time Block Codes (STBC) combined with a Reed Solomon (RS) - Convolutional concatenated coding scheme in order to provide reliable transmission of MPEG2 streams without strong reliance on ARQ. PER performances are presented and throughput enhancements are evaluated via link adaptation for different RS correction capabilities (8 and 32 bytes) and different STBC configurations (2Tx-1Rx and 2Tx-2Rx). The proposed system with a 2Tx-2Rx STBC and a 32 byte correction capability RS code allows a gain of 10dB over the standard performance of IEEE802.11a and 2dB over a 2Tx-2Rx STBC system for a PER of 10/sup -2/
