Abstract

Receiver is designed to meet the multipath channel condition to suppress narrowband interference. The technique used is MIMO-OFDM with QAM in UWB environment. MIMO provide spatial multiplexing which allows direct improvement of capacity by simultaneous transmission of multiple data stream. The emerging Ultra Wideband (UWB) system offers a great potential for the design of high speed short-range wireless communications. UWB has wide bandwidth but emits very less amount of energy. Hence, it does not interfere with other narrowband device signals. This reduced narrowband interference leads to improved SINR and decreased BER. A combination of space time frequency (STF) coding and hopping multiband OFDM modulation is also proposed to fully exploit all the available spatial and frequency diversities, which are innate in UWB environments.
