Abstract  Abstract

In a transmitter or transceiver signals can be precoded by multiplying symbol vectors with various matrices. For example symbol vectors can be multiplied with a first column subset of unitary matrix which spreads symbols in the symbol vectors across virtual transmit antennas a second diagonal matrix which changes a phase of the virtual transmit antennas and a third precoding matrix which distributes the transmission across the transmit antennas.
