In February 2002, the federal communications commission allocated 7500MHz of spectrum for unlicensed use of commercial Ultra-WideBand (UWB) for the purpose of communication. This spectral allocation has initiated an extremely productive activity for industry and academia. In this paper, the aim is to analyze the performance of MB-OFDM system with higher order QPSK/QAM mapping. This paper is to compare the performance of these two modulation techniques with an AWGN channel and the parameters considered are BER (Bit Error Rate) and PSD (Power Spectral Density) in the system.
