Eigenvector-Based Method and Apparatus for MIMO Equalizer Design via Linear Integer Forcing Architecture

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 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 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.
