Abstract
Official abstract text for this publication.
Processing data presented in the form of a vector representation involves representing direction of the vector with incremental accuracy by using a set of vector codebooks of decreasing dimensions per accuracy increment.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of encoding a channel signature of signals received by a mobile station from a plurality of antennas of a base station, the method comprising decomposing a matrix indicating the channel signature into at least a first vector, a second vector and a phase correction to the vectors; quantising the phase correction; and encoding the matrix as a plurality of indications, the plurality of indications being indicative of at least the first vector…
