Abstract
The invention is CDMA quadrature signal technology that controls the transmit power of a CDMA signal. The CDMA quadrature signal technology receives a CDMA signal, and in response, process quadrature components of the CDMA signal to generate a power control signal. The CDMA quadrature signal technology adjusts the gain of the CDMA signal in response to the power control signal. A CDMA transmitter transmits the CDMA signal after the gain is adjusted. One example of the CDMA transmitter is a CDMA base station. Using the invention, a multi-sector CDMA base station can control power without transferring gain information to base station components for all sectors. The invention eliminates unnecessary data transfer and storage.
