A transmitting and receiving method for limited feedback linear discrete code

This invention relates to one limit feedback linear discrete code emission and receive method, which is characterized by the following: storing same codes in receive and send ends and selecting current signal optimization codes according to codes selection rules and feed backing the codes to the emission end; emission end selects the optimization codes for linear discrete codes; using optimization for decoding on receive end; due to discrete codes and feedback linkage selecting linear discrete codes for coding.
