Abstract:
1. A method of processing a signal that simplifies computational complexity in estimating channel behavior and correcting signals transmitted over the channel the method comprising: a) receiving a signal transmitted over the channel, the signal comprising an information signal and at least a portion of a known signal; b) determining at least one indicator of channel characteristics based at least in part on the portion of the known signal; c) generating a first value indicative of the information signal based at least in part on the at least one indicator of the channel characteristics, wherein the first value comprises an error signal; and d) removing the error signal from the first value of the signal based at least in part on the portion of the known sign,; wherein determining at least one indicator of the channel characteristics comprises determining an estimate of the channel characteristics in the frequency domain, and wherein removing the error signal comprises determining a value indicative of the error signal by identifying filter tap locations of a filter based on the estimate of the channel characteristics, the known signal, the portion of the known signal as received and by determining coefficients of the filter for each of the filter tap locations based at least in part on a difference between the portion of the known signal as received and the known signal.
