Abstract :
Ultra wideband (UWB) radio is a new wireless technology that uses sub-nanosecond pulses to transmit information, resulting in a bandwidth greater than 1 GHz. The problem of synchronizing a receiver with the incoming signal grows in complexity as the signal bandwidth increases. This paper addresses coarse synchronization in UWB receivers. It analyzes how the design of the correlation process affects the time to achieve synchronization, highlighting the importance of the probability of false alarm in its performance.
