Abstract
The invention is a method and apparatus for determining the coefficients to be used by a time domain equalization circuit in a receiver in a communication system using discrete multitone (DMT) technology. The method and apparatus is particularly efficient in that the order of the channel response equation after channel shortening is less than or equal to the allotted cyclic prefix length utilized in the applicable communication protocol being used. Further, the invention includes an efficient method and apparatus for determining symbol synchronization for the time domain equalization.
