RADIO RECEIVER WITH AUTOCORRELATION SEPARATION OF FREQUENCY-SHIFT KEYED CONTINUOUS-PHASE SIGNAL TRANSMISSIONS Russian patent published in 2014 - IPC H04L29/00 H04L27/14 

FIELD: radio engineering, communication.

SUBSTANCE: radio receiver, which includes series-connected input amplifier, first frequency converter, solid-state main selection filter, intermediate frequency amplifier, second frequency converter, low-pass filter, limiting amplifier and comparator, the output of which is connected to the input of a digital delay line made in form of an N-bit shift register and a clock generator, also includes a D flip-flop. The data input of the D flip-flop is connected to the connection point of the output of the comparator and the input of the digital delay line; the clock input of the D flip-flop is connected to the output of the digital delay line and the output of the D flip-flop is the output of the radio receiver, wherein the number of bits of the shift register should ensure a delay time associated with symbol carrier frequencies by a defined ratio.

EFFECT: simple radio receiver with autocorrelation separation of frequency-shift keyed continuous-phase signal transmissions.
