WIRELESS BASE STATION WITH NEAR-FAR GAIN COMPENSATION

摘要

A wireless base station receiver (10a) receives weak signals from mobile units (22) at a first position using a first receiver configuration and strong signals from mobile units at a second position using a second receiver configuration. The base station receiver (10a) includes an input terminal to receive an inbound signal from each mobile unit (22). A diplexer (58) is coupled to the input terminal and configured to receive the inbound signal and to pass a first frequency band of the inbound signal as a first signal, and to pass a second frequency band of the inbound signal as a second signal. An attenuator (64) is coupled to the diplexer and configured to attenuate the second signal to create a third signal. A downconverter (68) is coupled to the diplexer (58) and the attenuator (64) and configured to downconvert the first signal and the third signal to provide a downconverted inbound signal. An analog-to-digital converter (70) is coupled to the downconverter (68) and configured to convert the downconverted inbound signal to a digital signal. Advantages of the invention include the ability to compensate for the gain required to receive inbound signals from near and far mobile units.
