Patent ID: 7839923

Claim:
A communications system comprising: a carrier recovery module that determines a carrier frequency offset of an input signal; a rotator module that (i) rotates the input signal to minimize the carrier frequency offset and (ii) generates a compensated signal; a correlator module that correlates the compensated signal with a unique word to obtain a timing correction; and an equalizer module that (i) equalizes the compensated signal based on the timing correction and (ii) generates an equalized signal, wherein said carrier recovery module comprises: a burst detector module that detects a burst in response to a preamble of the input signal; and an average detector to set a gain of a programmable gain amplifier (PGA), wherein the average detector is (i) disabled during burst search by the burst detector module and (ii) enabled at a beginning of each burst, outputs burst data to a digital signal processor when the average detector is enabled, and does not output the burst data to the digital signal processor when the average detector is disabled.
