Abstract

Outdoor physical layer performance results are presented for a proposed 4G coded orthogonal frequency division multiplexing (COFDM) system. The transceiver employs space-time processing and results are obtained using measured wideband MIMO channels. Gains as high as 10.5 dB are observed using 2Tx and 2Rx antennas for 1/2 rate coded QPSK at a packet error rate (PER) of 10^-2. Additionally, results are compared for spatial and polarisation diversity.
