METHOD AND APPARATUS TO PROVIDE MULTIPLE-MODE SPATIAL PROCESSING IN A RADIO RECEIVER
First Claim
1. A radio receiver comprising:
- a receive processing unit coupled to process signals received from an antenna array by applying a selected spatial processing mode of a plurality of spatial processing modes of one or more spatial processing methods; and
a selector coupled to the receive processing unit to select the spatial processing mode from the plurality of spatial processing modes, including selecting the spatial processing method in the case that the set of spatial processing modes are of more than one spatial processing method.

Abstract
Methods and apparatuses, including computer program products, for spatial processing in a radio receiver. One embodiment is a radio receiver for operation in a wireless communication system. The radio receiver may include a receive processing unit to process signals received by an antenna array by applying a selected spatial processing mode of a plurality of spatial processing modes. The modes include one or more modes of one or more spatial processing methods. The receiver also includes a selector to select the spatial processing mode from the plurality of spatial processing modes. The selecting includes selecting the spatial processing method in the case that the set of spatial processing modes are of more than one spatial processing method.
