1. A wireless device comprising:

  • a first transmit signal path operable to generate a first radio frequency (RF) output signal for transmission from a first antenna;

    a second transmit signal path operable to generate a second RF output signal for transmission from a second antenna, the first and second antennas being transmit antennas and being de-correlated with respect to each other; and

    a controller operable to selectively enable the first transmit signal path, the second transmit signal path, or both the first and second transmit signal paths to achieve a higher received signal level at a receiver, wherein the first and second transmit signal paths are selectively disabled based on transmit power control (TPC) commands received by the wireless device.
