Abstract :
This paper investigates the operation of noncoherent detectors for UWB applications. Binary pulse-position modulation is assumed and it is shown that, if no channel information is exploited for detection purposes, application of the generalized maximum ratio test leads to an energy capture receiver. A simple synchronization scheme is proposed for such a receiver, and its performance is assessed by simulation over realistic multipath channels. Bit-error-rate degradations due to synchronization errors are found to be marginal.
