Abstract:
In a method for producing antenna element signals for transmitting a serial traffic channel from a plurality of elements in an antenna array, data in the serial traffic channel is converted to data in two or more parallel traffic channels. Thereafter, data in the two or more parallel traffic channels are spread with different spreading codes to produce spread traffic signals. The spread traffic signals are combined to produce combined signals, which are each modified according to adaptive array weights to produce element signals. A pilot signal is then added to at least one of the element signals to produce two or more antenna element signals.
