Abstract
A wireless base station receiver receives weak signals from mobile units 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 includes an input terminal to receive an inbound signal from each mobile unit. A diplexer 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 is coupled to the diplexer and configured to attenuate the second signal to create a third signal. A downconverter is coupled to the diplexer and the attenuator and configured to downconvert the first signal and the third signal to provide a downconverted inbound signal. An analog to digital converter coupled to the downconverter and configured to convert the down converted 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.
