DEVICE AND METHOD FOR RECEIVING BINARY DATA RADIO FREQUENCY

摘要

The invention relates to a device and method for receiving binary data radio frequency in a radio frequency transmitting channel, wherein the inventive device comprises pick-up means provided with an antenna and a main filter, whose main band-pass corresponds to said transmitting channel, and a correlation receiver, in which a frequency diversity receiver (3) comprising a plurality of parallel channels (VF1 to VFn) is used, wherein each channel is provided with a secondary filter (Fs1), respectively, whose input is connected to the main filter (Fp) output, matched envelop detection and filtering (Fa1) circuits connected to a secondary filter output and a summing circuit (7) whose input is connected to the outputs of said envelop detection and matched filtering circuits and output is connected to the input of said correlation receiver (4). The band-pass of said secondary filters correspond to disjointed sub-bands included into said main band-pass. The matched envelop detection and filtering circuits are used for detecting desired-shape pulses in signals received from the secondary filters. The summing circuit is used for adding the signal received form the matched envelop detection and filtering circuits and for transmitting a resulting signal to the correlation receiver.
