METHOD OF MONITORING BROADBAND SIGNAL DELAY AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2013 - IPC H04B1/10 

FIELD: radio engineering, communication.

SUBSTANCE: method of monitoring broadband signal delay involves generating two signals and filtering the obtained signals, the amplitude of which is proportional to the value of the correlation function between the reference signal and the received signal; comparing the obtained signals and correcting the time position of the reference signal relative to the received signal, and inverting the received signal before filtering, and switching the inverted and non-inverted signals, wherein a signal sample is formed, representing a keying pseudorandom sequence of binary symbols; a copy of the signal sample with a different time shift is formed from the signal sample; further, signals without broadband keying are generated form the non-inverted and inverted components of the original received signal. If a binary symbol of the copy of the signal sample is equal to 1, an inverted component of the received signal is used; if the binary symbol of the copy of the signal sample is equal to 0, an non-inverted component of the signal is used.

EFFECT: reducing losses associated with signal multiplication and simple processing scheme.
