Abstract :
This work analyzes the performance of a proposed multiband DS-UWB system. We take a RAKE receiver to tackle the frequency selectivity of each subband. By combining the output of every RAKE receiver with the MRC method, we get maximal signal to noise ratio. The proposed system has the advantage of low peak-to-average power ratio and shows robustness to multiuser interference and narrowband interference.
