Patent ID: 8175188

Claim:
An apparatus comprising: a first unit operatively enabled to establish a set of precoder parameters based at least in part from a parametric channel model for a bandlimited wireline communication channel carrying a sequence of N-element time domain signal vectors where N is an integer, and where the signal vectors do not include respective cyclic prefixes; a second unit operatively enabled to establish one or more frequency-domain encoded data blocks to be transformed to one or more precoded data vectors, wherein the precoded data vectors cause a measure of inter-vector distortion to be reduced at a receiver, the second unit using the set of precoder parameter to compute a precoding mathematical operation in an orthogonal transform domain wherein a plurality of precoding cross terms are eliminated to reduce computational requirements during one or more order-of-N-squared matrix multiplication operations; and a third unit operatively enabled to establish a time domain signal vector based at least in part on at least one of the one or more precoded data vectors.
