COMMUNICATION RADIO RECEIVER WITH ADAPTIVE COMPENSATOR Russian patent published in 2013 - IPC H04L25/03 

FIELD: radio engineering, communication.

SUBSTANCE: method of estimating a transmitted signal in a wireless communication system involves receiving a wireless signal containing a pilot channel and at least another channel, estimating the transmitted signal using a compensator and the received wireless signal. The compensator includes a filter with a plurality of tap-offs, which can be tuned using an adaptive algorithm which employs the estimated pilot signal from the received wireless signal; the estimated pilot signal is extracted; the estimated pilot signal is delivered to the adaptive algorithm and the plurality of tap-offs are tuned using the adaptive algorithm. The plurality of tap-offs is tuned using the adaptive algorithm in each N-th symbol interval of the pilot signal, where N is a positive integer, wherein the value of N varies based on the speed at which the device moves in the wireless communication system.

EFFECT: improved radio receiver.
