METHOD FOR DATA TRANSMISSION AND RECEIVE USING BASED ON PHASE SHIFT OF PRECODING AND TRANSCEIVER TO SUPPORT SAME Russian patent published in 2012 - IPC H04B7/02 

FIELD: information technology.

SUBSTANCE: method for signal transmission in transmitter of MIMO system using multiple antennas includes coding the input signals of encoder in order to output multiple streams, precoding multiple streams in preliminary encoder in order to represent multiple streams on multiple antennas using specific precoding matrix selected from the first codebook, transmission of signals represented on antennas to receiver. The first codebook includes (N_restrict) precoding matrices and is subset of base codebook which includes (N_c) precoding matrices where (N_restrict)<(N_c). Each of (N_restrict) matrices has (i) index, (i)=0, 1, …, (N_restrict)-1. Specific precoding matrix is selected according to (i)=(s)mod(N_restrict)> where (s) is variable changing each of (v) continuous subcarriers or virtual resources, where (v) is integral value.

EFFECT: improved efficiency of communication.
