Apparatus and associated method for operating upon data signals received at a receiving station of a fixed wireless access communication system
DCFirst Claim
1. An apparatus for a communication station operable in a wireless communication system at least to receive first and second data signals successively transmitted thereto by a first subscriber station and a second subscriber station, respectively, within a plurality of subscriber stations, the apparatus comprising:
- a first demodulator selectably coupled to receive the first data signals transmitted to the communication station;
at least a second demodulator also selectably coupled to receive the second data signals transmitted to the communication station; and
a controller, coupled to the first demodulator and to the at least second demodulator in a feedback arrangement, the controller alternately selecting the first data signals for application to the first demodulator and the second data signals for application to the second demodulator,wherein the at least the second subscriber station comprises a plurality of subscriber stations and wherein the controller selectively applies the first and second data signals to the first and second demodulators according to a selected pattern by alternately coupling the first demodulator and the second demodulator to receive, selectably, the first and at least second data signals communicated by alternating ones of the plurality of subscriber stations.

Abstract
Apparatus, and an associated method, for acting upon data signals received at a base station of a fixed wireless access communication system. A plurality of modems are positioned at the base station, and a controller controls to which modem that a data signal, transmitted by a particular subscriber station, is applied to a particular modem. Profiles relating to channel and signal characteristics are also maintained and used by the modem during demodulation operations.

4. An apparatus for a communication station operable in a wireless communication system at least to receive first and second data signals successively transmitted thereto by a first subscriber station a second subscriber station, respectively, within a plurality of subscriber stations, the apparatus comprising:
-
a first demodulator selectably coupled to receive the first data signals transmitted to the communication station; at least a second demodulator also selectably coupled to receive the second data signals transmitted to the communication station; and a controller, coupled to the first demodulator and to the at least second demodulator in a feedback arrangement, the controller alternately selecting the first data signals for application to the first demodulator and the second data signals for application to the second demodulator, wherein the first and at least second data signals transmitted to the communication station by the first and at least second subscriber stations are transmitted in bursts of selected time durations and wherein the controller further determines times of arrival and time directions of the bursts which form the data signals, wherein the at least the second subscriber station comprises a plurality of subscriber stations and wherein said controller selectively applies the first and second data signals to the first and second demodulators according to a selected pattern by alternately coupling the first demodulator and the second demodulator to receive, selectably, the first and at least second data signals communicated by alternating ones of the plurality of subscriber stations.

16. A method for acting upon first and second successive data signals transmitted to a communication station operable in a wireless communication system by a first subscriber station and at least a second subscriber station, the method comprising:
-
selecting at which of a first demodulator and at least a second demodulator to apply at least one of the first data signals and the second data signals, wherein the first and second successive data signals and any subsequent data signals are alternately applied to the first and second demodulators; demodulating the at least one of the first and at least second data signals at the first demodulator when the first demodulator is selected during the operation of selecting; and demodulating the at least one of the first and at least second data signals at the second demodulator when the second demodulator is selected during the operation of selecting; and maintaining profiles associated with each of the first and at least second data signals transmitted upon the first and at least second channels, respectively, and wherein the operations of demodulating further comprise accessing the profiles. - View Dependent Claims (17)
