The paper is concerned with timing recovery for ultra-wideband communications operating in a dense multipath environment. A timing algorithm is proposed that exploits the samples of the received signal to estimate the start of the individual frames with respect to a local reference (frame timing) and the location of the first frame in each symbol (symbol timing). Channel estimation is inherent in the timing algorithm and can be used for coherent matched filter detection.
