Multiband-OFDM based ultra wideband system modelling of on/off-body antenna diversity

This paper presents system level performance of ultra wideband (UWB) on-body and off-body diversity using multiband OFDM based UWB system on the basis of bit error rate (BER). The percentage improvement in the system performance of diversity combined signal with respect to the single antenna signal shows that; in case of off-body diversity case, improvement variations in BER performance are in the range of 25% (for chest case i.e., LOS scenario) to 65% (for back case i.e., NLOS scenario) higher than that of on-body diversity.
