Propagation Assessment of MB-OFDM Ultrawide Band (UWB) MIMO Based Communication in Fading Channels

Abstract: 

Over the last few years OFDM has gained wide popularity in the wireless world for its robustness against multipath interference, ability to capture multipath energy efficiently, ability to allow frequency diversity with the use of efficient forward error correction (FEC) coding, and ability to provide high bandwidth efficiency through the use of sub-band adaptive modulation and coding techniques. This research work provides performance analysis of multiband orthogonal frequency division multiplexing (MB-OFDM) UWB MIMO system MATLAB simulations. The research work indicates that it is totally impossible to predict the performance of UWB system in Lognormal channel. In multiple interference, the performance of UWB communication systems with the same noise power in Nakagami-m fading channel outperforms that of Lognormal fading channel also the BER performance of UWB communication system is better in TH multiple interference than DS multiple interference from the results shown and it is important to stress here that the performance of MB-OFDM UWB MIMO system with the same transmitted power performs poorly as compare to that MB-OFDM UWB system MB-OFDM UWB when the number of interferes is 10.
