Abstract:
A wireless base station receiver for receiving 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, said base station receiver comprising:an input terminal to receive an inbound signal from each of said mobile units;a diplexer coupled to said input terminal and configured to receive said inbound signal and pass to a first frequency band of said inbound signal as a first signal, and to pass a second frequency band of said inbound signal as a second signal, wherein the first frequency band is associated with far mobile units, and the second frequency band is associated with near mobile units;a downconverter coupled to said diplexer and configured to downconvert said first signal and said second signal to provide a downconverted inbound signal;an analog to digital converter coupled to said downconverter and configured to convert said down converted inbound signal to a digital signal; anda processor coupled to said analog to digital converter and configured to receive said digital signal, and configured to assign each mobile unit a weak signal frequency in said first frequency band when the mobile unit has a weak signal strength, and assign each mobile unit a strong signal frequency in said second frequency band when the mobile unit has a strong signal strength.
