<p>The present invention is a novel and improved method and apparatus for control transmission energy. The present invention describes a closed loop power control system that operates in conjunction with a transmitter (64, 66) using orthogonal transmit diversity. In a first embodiment of the present invention, the receiver evaluates the signal to noise ratio (SNR) of the two components of the signal. A weighted sum of these two components emphasizing the weaker of the two signals is generated and used in the generation of the power control commands. In a second embodiment of the present invention, the SNR of the two component signals are calculated and two separate power control commands are generated based on a corresponding one of the calculated SNR values.</p> |
