First Claim
Patent Images
1. A remote unit, comprising:
- a spatial processing unit to couple to a plurality of antennas, the spatial processing unit having a logic unit to perform spatial processing of signals received by the plurality of antennas, the spatial processing to include spatial combining of selectively weighted versions of signals received on the antennas;
a plurality of receive paths, each receive path to couple between one of the plurality of antennas and the spatial processing unit, wherein the receive path includes components for processing received signals;
logic to determine a number of the plurality of the receive paths to enable for spatial processing; and
a controller to enable and disable one or more of the plurality of receive paths depending on the determined number.

22. A remote unit, comprising:
-
a spatial processing unit including a processor and receive paths to couple to a plurality of antennas having diversity, the spatial processing unit to combine weighted versions of a signal received on the antennas; a performance estimation unit to estimate performance of the remote unit, including periodically causing the remote unit to operate in a non-spatial processing mode and measuring a performance level of the remote unit while the remote unit is operating in a non-spatial processing mode; and a power conservation unit to selectively enable and disable at least a portion of the spatial processing unit based on the performance estimated by the performance estimation unit. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
