摘要： Certain aspects of the method may comprise generating at least one control signal that may be utilized to control at least a first of a plurality of received spatially multiplexed communication signals. An amplitude and/or phase of the first received spatially multiplexed communication signal may be adjusted via the generated control signal so that the amplitude and/or phase of the first received spatially multiplexed communication signal may be equivalent to an amplitude and/or phase of a second received spatially multiplexed communication signal. The amplitude of the first received spatially multiplexed communication signal is adjusted within the processing path used to process the first received spatially multiplexed communication signal.

摘要： In a RF communications system, aspects for implementing a single weight single channel MIMO system with no insertion loss may comprise generating at least one control signal that is utilized to control at least one of a plurality of received signals in a WCDMA and/or HSDPA system. A phase of a first of the plurality of received signals may be adjusted outside of a first processing path used to process that signal so that it is equivalent to a phase of at least a second of the plurality of received signals. A gain in the first processing path may be equivalent to a gain in a second processing path that is utilized to process the second of the plurality of received signals. The control signal may be utilized to adjust a phase and/or an amplitude of at least one of a plurality of received signals.
