Abstract—Next generation communication systems aim mainly to data throughput improvement for any wireless channel conditions. According to Shannon formula, UWB system with gigahertz band can reach ultra-high data transmission rate. Multiband orthogonal frequency division multiplexing (MB-OFDM) for ultra wideband (UWB) technology presents a potential candidate for the diverse set of high-rate performance short-range applications. When combined with a multiple-input multiple-output (MIMO) and a space time code (STC) transmission scheme, MB-OFDM UWB presents a viable way to improve channel capacity and expand coverage area. This paper presents an analysis on the capacity and performance of MIMO STC-MB-OFDM systems over UWB channels. Also, this work will compare the Alamouti code and the algebraic space–time–code (ASTC) capacity when used in MIMO MB-OFDM system. It will be shown that ASTC code can provide significantly higher channel capacity and better BER performance when used in a MIMO MB-OFDM system.

Index Terms—BER, channel capacity, MB-OFDM UWB, MIMO, STC.
