A wireless communication network (10) includes a wireless transmitter having a plurality of antennas (AT11, AT12). The transmitter includes for each of a plurality of different user channels (Dn), circuitry (22n) for providing a plurality of groups of symbols in a first symbol group sequence (D1n). Each of the plurality of different user channels includes circuitry (241n) for forming a first modulated symbol group sequence for the user channel by modulating the symbols in the first symbol group sequence with a unique code that corresponds to the user channel and distinguishes the user channel from each other of the plurality of different user channels and circuitry (261) for combining the first modulated symbol group sequences for transmission by a first antenna (AT11). Each of the plurality of different user channels includes circuitry (22n) for forming a second symbol group sequence (D2n) by time reversing symbols in at least some of the groups of symbols.
