Method of acquiring initial synchronization in impulse wireless communication and receiver

A receiver in an impulse wireless communication. The receiver includes a pulse-pair correlator that receives a signal and divides it into two signals for paths. One of the signals is input to signal multiplier while another signal is delayed by a delay unit. The signal multiplier multiplies the received signal by a delayed signal. An integrator integrates an output signal over a designated period of time. An adding module sums an output signal from the integrator. An acquiring module compares an summing-up output from the adding module with a predetermined threshold value to detect the existence of a transmitting-standard preamble.
