Classification: CPC H | IPC H

Claim 18:
19. A user equipment in a communication network, the user equipment comprising:
a transceiver including a selectable baseline receiver, and a selectable alternative receiver, that receives a set of reference signals; and
a controller that estimates a set of channel signatures for a multiple antenna communication channel, based on the received set of reference signals, and calculates channel state information including a set of quality metrics;
wherein the controller selects the selectable baseline receiver for the multiple antenna communication channel at the user equipment, in response to the set of quality metrics satisfying a criterion, and the controller selects the selectable alternative receiver for the multiple antenna communication channel at the user equipment, in response to the set of quality metrics not satisfying a criterion; and
wherein the selectable alternative receiver for the multiple antenna communication channel at the user equipment is based on a set of integer linear combinations, where each integer linear combination is based on at least a pair of channel signatures from the estimated set of channel signatures.
