Patent ID: 7512199

Claim:
A channel estimation processing module, comprising: a first main channel estimator operable to: receive Radio Frequency (RF) burst(s) and known sequences within the received RF burst(s); and produce a main channel impulse response based on the received RF burst(s) and known sequences within the received RF burst(s); a signal estimator operable to: receive the main channel impulse response and known sequences within the received RF burst(s); and produce an estimated signal from the main channel impulse response and known sequences within the received RF burst(s); a first combiner operable to subtract the estimated signal from the received RF burst(s); a data recovery module operable to recover data from an output of the first combiner; a disturber channel estimator operable to: receive the output of the first combiner and recovered data; and produce a disturber channel impulse response based on the output of the first combiner and recovered data; a disturber signal estimator operable to: receive the disturber channel impulse response and recovered data; and produce an estimated disturber signal from the disturber channel impulse response based and recovered data; a second combiner operable to subtract the estimated disturber signal from the received RF burst(s); and a second main channel estimator operable to produce an improved main channel impulse response based on the output of the second combiner.
