In a transmitter or transceiver, symbol vectors (514), each comprising two or more symbols, are multiplied, in the following order, with a first column subset of unitary matrix (518) which spreads symbols in the symbol vectors across virtual transmit antennas, with a second diagonal cyclic delay diversity matrix (516) which changes a phase of the virtual transmit antennas, and with a third precoding matrix (515) which distributes the transmission across a plurality of transmit antennas (522). |
