Abstract

Recent study in information-theory has demonstrated the enormous capacity potential of wireless communication system with multiple transmit and receive antennas. As a result, a number of layered space-time (BLAST) architectures have been proposed. In this paper, the capacity of narrowband and wideband (OFDM) systems in scattering channel models are analysed via Monte-Carlo simulations. In particular, we show that OFDM based MIMO system can combat pin-hole effect which degrades capacity.
