ABSTRACT:
A communications receiver (103) comprising a carrier recovery apparatus having an adjustable response time loop filter (123) responsive to carrier signal parameters determined by a signal processor (141) is disclosed. Signal reception under fading conditions is improved by detecting the received signal parameters in an energy level determinator (207), a rate of change of energy level determinator (209) and a look-up table value (221) corresponding to a position of TDMA time clock (219).
