In this paper, we study a MB-OFDM UWB system using reduced complexity decoding algorithm for LDPC codes. Focusing on the system simulation and performance analysis, we design a high rate MB-OFDM UWB system and run a complete simulation for such system over the additive white Gaussian noise(AWGN) channel and IEEE UWB channel. Simulation results show that the bit error rate (BER) performance of such UWB system is better, and illustrate that the use of reduced- complexity decoding algorithm for LDPC codes in MB-OFDM UWB system is quite feasible.
