M-PSK MB-OFDM Ultra Wideband communication system performance for 4G high-rate IEEE 802.15.3a Wireless Personal Area Networks

The emerging Ultra Wideband (UWB) communication system is highly suitable for wireless multimedia connectivity in home and SOHO (Small Office Home Office) scenarios. As such, UWB is an example of enabling technology for Fourth Generation (4G) communication systems designed to replace Bluetooth communications. Indeed, UWB radio will revolutionise Wireless Personal Area Networks (WPANs) allowing the wireless transmissions of high data rates (hundreds of Mbps) over short distances (0–10 m). This paper deals with the design and performance of M-ary PSK based Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) UWB communication system over realistic multipath-fading modified Saleh-Valenzuela (S-V) channel environments as specified by the IEEE 802.15.3a Task Group. A system level analysis is addressed to improve the throughput and transmission range as a function of coded BER, link PER, received SNR and distance through extensive Monte Carlo simulations.
