Abstract:
A system for enabling efficient utilization of available bandwidth through overlapping adjacent channels comprising:a receiver for receiving a waveform having data information associated with a plurality of channels and noise information; a filter bank adapted to: receive said waveform, generate channel information, said channel information including a first estimate of the data information on a first channel and adjacent channel interference information associated with the first channel, and output the channel information; at least one decoder adapted to receive said channel information and calculate an estimated interference value; logic configured to calculate a feed-back coefficient and a feed-forward coefficient based on an output from the at least one decoder; and an interference canceler configured to: receive said output channel information, said estimated interference value and said feed-back and feed-forward coefficients, subtract the estimated interference value from the channel information, and generate a second estimate of the data information using the feed-back and feed-forward coefficients.
