Capacity comparison of UWB system based on combined Cosinusoid Gaussian pulse

This paper studies the channel capacity with respect to Cosinusoid Gaussian serial pulses of MPPM-TH-UWB communication systems under additive white Gaussian noise (AWGN) channel. It mainly makes comparison between optimum combined cosinusoid gaussian pulse and 2nd devative Gaussian pulse conforming to the FCC regulations. The simulation results demonstrate that the capacity is influenced by variance of various pulses autocorrelation function. This conclusion is helpful for the pulse analysis and selection for UWB systems.
