| Zusammenfassung: | A method of conditioning Orthogonal Frequency Division Multiplexed (OFDM) signals for transmission by multiple antenna (6a,b) transmitters or transceivers includes determining antenna-sub-carrier allocations (9) and then phase pre-coding transmitted signals (11a,b) to produce an effective channel at the receiver which meets one or more criteria in terms of its frequency response. The one or more criteria may correspond to a transmission from fewer transmitters as expected by legacy receivers. A transmitter and transceiver are also described. |
