RECEIVER IN A WIRELESS COMMUNICATIONS SYSTEM FOR RECEIVING SIGNALS HAVING COMBINED ORTHOGONAL TRANSMIT DIVERSITY AND ADAPTIVE ARRAY TECHNIQUES

摘要

In a method for producing antenna element signals (112 and 114) for transmitting a serial traffic channel (58) from a plurality of elements (116 and 118) in an antenna array, data in the serial traffic channel is converte d to data in two or more parallel traffic channels (64 and 66). Thereafter, da ta in the two or more parallel traffic channels are spread with different spreading codes (68 and 70) to produce spread traffic signals (72 and 74). T he spread traffic signals are combined to produce combined signals (80), which are each modified according to adaptive array weigths (90 and 92) to produce element signals (94 and 96). A pilot signal is then added (98) to at least o ne of the element signals to produce two or more antenna element signals (94 an d 96).
