This paper investigates a design and performance of 4-parallel MB-OFDM UWB receiver. The performance of the proposed MB-OFDM UWB receiver using a 4-parallel synchronization structure is degraded by 0.25 dB compared with that of a receiver using a 1-parallel synchronization structure in the maximum frequency/sampling clock offset tolerance in an AWGN channel. Considering other impairments, including imperfect synchronization algorithms, the effect of quantization error by the 4-parallel synchronization structure is negligible in a multi-path channel environment as well as in an AWGN channel, as identified in simulation results.
