ABSTRACT:
A multiple receiving antennae system having a plurality of radio frequency (RF) modules being responsive to incoming signals for processing the same to generate baseband signals. The multiple receiving antennae system further processes baseband signals to generate digital baseband signals, in accordance with an embodiment of the present invention. The multiple receiving antennae system further still includes a plurality of automatic gain control (AGC) modules being responsive to digital baseband signals for processing the same to generate a plurality of gain values. The plurality of gain values are used in the plurality of RF modules for independent gain adjustment of the incoming signals. The plurality of gain values are used to generate adjusted signals with enhanced signal to noise ratio (SNR) to improve the performance of the multiple receiving antennae system, whereby the plurality of gain values are used to enhance reception of incoming signals by improving SNR.
