Patent ID: 8515339

Claim:
A master system unit for use in a wireless communication system, the master system unit including an input port, an output port, a plurality of bi-directional ports, a combiner/splitter, and a processor, the combiner/splitter further comprising: a) a splitter coupled to the input port and configured to provide a plurality of separate signals based, at least in part, on a received signal; b) a combiner coupled to the output port and configured to combine a plurality of adjusted signals; c) a first circuit comprising a first attenuator coupled to the splitter and configured to attenuate a first one of said separate signals based, at least in part, on a first gain parameter and a first amplifier configured to amplify said attenuated first one of said separate signals, the first amplifier being coupled to a first duplexer, the first duplexer being coupled to a first one of the plurality of bi-directional ports and a second amplifier configured to amplify a first signal received from said first one of the bi-directional ports, the second amplifier being coupled to a second attenuator configured to attenuate said amplified first signals received from said first one of the bi-directional ports, to provide a first one of said adjusted signals based, at least in part, on a second gain parameter, the second attenuator being coupled to the combiner; and d) a second circuit comprising a third attenuator coupled to the splitter and configured to attenuate a second one of said separate signals based, at least in part, on a third gain parameter and a third amplifier configured to amplify said attenuated second one of said separate signals, the third amplifier being coupled to a second duplexer, the second duplexer being coupled to a second one of the plurality of bi-directional ports and a fourth amplifier configured to amplify a second signal received from said second one of the bi-directional ports, the fourth amplifier being coupled to a fourth attenuator configured to attenuate said amplified second signal received from said second one of the bi-directional ports, to provide a second one of said adjusted signals based, at least in part, on a fourth gain parameter, the fourth attenuator being coupled to the combiner; the processor being configured to automatically adjust an amount of gain applied individually to said separate signals and said adjusted signals by determining said first, second, third and fourth gain parameters, wherein at least one of the plurality of bi-directional ports is configured to pass an intermediate-frequency (IF) signal; and wherein the master system unit further comprises a user port configured to communicatively couple the processor and a user, wherein the user port is further configured to exchange information between the processor and the user including communication allowing the user to provide information to the processor.
