Abstract
A wireless transmission system supporting at least first and second high-isolation transmission modes. In the first TX mode, first and second incoming data streams are processed independently within first and second TX paths to generate first and second analog outgoing signals for separate transmission via first and second antennas. In the second TX mode, the two incoming data streams are combined to form a combined data stream. First and second versions of the combined data stream are processed by the first and second TX paths to generate two analog signals that are combined for transmission via a single antenna. In the second TX mode, a feedback signal, based on differences between the two analog signals, is used to adjust the relative phase and/or delay of the two versions of the combined signal in the digital domain to reduce phase differences between the two analog signals, thereby increasing signal transmission power.
