Abstract
An rf signal transmitter for transmitting rf signals through a plurality of antennas is described, which comprises: a transmit section adapted to selectively set, with respect to an input signal, the initial phase of an output to at least one of said antennas depending on a time or frequency region used for communication and to provide delay to the output on an antenna-by-antenna basis and on the basis of a transmission timing or a transmission frequency; and a quality information receive section for receiving quality information from destination station, i.e., a wireless terminal unit, said quality information concerning the rf signal transmitted from said transmit section and received at said destination station.
