Digital point to multi-point transmission interference reduction signal processing procedure uses shaping vector selected to minimise Euclidean norm of difference vector

摘要

A digital point to multi-point transmission (d) interference reduction signal (x) processing procedure using K channels for K users first compensates interference by optimising the signal vector (x) using a scaled interference vector and a shaping vector (Bc-1) in K dimensional complex integer signal space selected to minimise the Euclidean norm of the difference vector.
