N2 - Dual Carrier Modulation (DCM) is widely used as the higher data rate modulation technique for Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) Ultra Wideband (UWB) in European Computer Manufacture Association (ECMA-368) standard. DCM is one of the high data rate modulation technique that provides a significant frequency diversity improvement by modulating the information symbols across non-adjacent subcarriers of OFDM modulator. Based on DCM constellation, possible union bound on Bit Error Rate (BER) is derived within the presence of Nakagami-m fading channel with fading parameter m. DCM for MB-OFDM UWB system provides approximately 3 dB less noise floor compared to the Quadrature Phase Shift Keying (QPSK) over acceptable BER. Interestingly, depending on number of paths, the BER performance decreases with increasing the fading parameter.
