The next generation mobile communication-4G will support high data transmission rate and high frequency efficiency. In order to satisfy the future requirements of wireless access systems, UWB, IMO, OFDM are the most competitive technologies in future wireless communication systems. This paper describes the use of adaptive modulated multi-input multi-output orthogonal frequency division multiplexing to enable effective communications in UWB systems with low signal-to-noise requirements. On the research of adaptive power and bits allocation scheme in modulated MIMO-OFDM for UWB communication system, an adaptive resource allocation algorithm based on sequential allocation is proposed. The simulation results suggest that the scheme is much simpler and more practical than the optimal allocation scheme at the small expense of performance.
