Abstract:
1. A system for channel equalization comprising: a first filter configured to utilize one or more first filter coefficients, the first filter comprising mixed phase filter and configured to output a first filter output; a second filter having one or more second filter coefficients based on the transfer function of the channel, the second filter configured to filter an error signal and output a filtered error signal; and a third filter comprising a feedback filter having one or more third filter coefficients, the third filter comprising a minimum phase filter and is configured to output a third filter output; a first junction configured to subtract the filtered error signal and the third filter output from the first filter output to create a decision device input; a decision device configured to receive the decision device input and create a decision device output; and a second junction configured to create the error signal based on the decision device input and the decision device output, wherein the first, second, and third filters are located in a receiver.
