Abstract
Multi-band orthogonal frequency division multiplexing ultra-wideband (MB OFDM UWB) communication system has been a leading proposal in the IEEE 802.15.3a standard and has been adopted in the ECMA standard for wireless personal area networks. In this paper, the performance of the MB-OFDM UWB communication system in the Saleh-Valenzuela multi-path UWB channel model using different antenna scheme configurations has been analytically evaluated. The analytical evaluation has been investigated for the three antenna scheme configurations which are the single input multiple output (SIMO), the multiple input single output (MISO), and the multiple input multiple output (MIMO). The issue of existence of high power inband interference signal such as the IEEE802.11n has been also analytically evaluated. A practical link budget analysis is considered. It was shown that the performance of the desired MB-OFDM UWB SIMO/MISO/MIMO communication system can severely deteriorated due to presence of such high power inband interference signal. The obtained analytical results are validated with the aid of extensive simulation results.
