DS-SS UWB wireless personal area network: BER and PER evaluation under an MMSE receiver

This paper focuses on the performance evaluation of a Direct Sequence - Spread Spectrum (DS-SS) Ultra Wideband (UWB) network in an indoor environment where receiver and transmitter positions are fixed. In particular, a novel distance and time dependent impulse response has been obtained and considered for our performance evaluation. Moreover, from receiver side, a Minimum Mean Square Error (MMSE) receiver has been considered in order to get the Bit Error Rate (BER) and Packet Error Rate (PER) estimation in many simulation conditions where distance, data rates and noise level are changed. PER analysis has been carried out by using a polynomial regression technique, through the Matlab tool, on simulation results. BER and PER vs. transmitter-receiver distance and number of users performance evaluations have been outlined.
