Synchronization is a critical factor in most communication systems, especially in Ultra-wideband (UWB) transmission. The difficulty of synchronization is accentuated in UWB due to the fact that the information-bearing waveforms are impulse-like and have low power. Moreover, the dense multipath channel, through which these low-power narrow pulses propagate, is unknown at the receiver during the synchronization...
This paper deals with timing acquisition in ultra-wideband communications operating in a dense multipath environment. A novel symbol and frame synchronization algorithm is proposed based on the maximum-likelihood criterion. And it 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...
