Receiver of pulses of an ultra wide band type signal and associated method

摘要

A receiver of electromagnetic and a method for receiving electromagnetic signals transmitted in a frequency band having a predetermined upper limit fMAX and representing a stream of information by means of a modulation of pulses at a predetermined average pulse repetition frequency fPRP. The receiver includes an input stage including a band-pass filter and applys processing without changing frequency of the signals and a sampler of the processed signals operating at a sampling frequency fe that is an integer multiple of the average pulse repetition frequency fPRP and less than said upper limit fMAX.

1. A receiver of electromagnetic signals, where each signal is transmitted with a corresponding frequency in a frequency band having a predetermined upper limit (fMAX) and representing a stream of information by means of a modulation of pulses at a predetermined average pulse repetition frequency (fPRP) using differential coding, the receiver comprising:
an input stage receiving the signals from an antenna, the input stage comprising a band-pass filter transmitting signals limited to the frequency band, the input stage applying processing without changing the frequency of the transmitted signals; and a sampler of the signals processed by the input stage, wherein the sampler applies a sampling frequency (fe) that is an integer multiple of the average pulse repetition frequency (fPRP) and less than the upper limit of the frequency band (fMAX), and wherein differential decoding of the signals comprises using a correlation module that is coupled to the sampler and auto-correlates the signals using a coupled memory that stores grouped samples from a preceding average pulse repetition period, where the integer is directly related to a number of the grouped samples.
