Patent ID: 7961782

Claim:
An interference suppression processing unit, comprising: N a ≧2 receiver paths configured to transmit respective N a ≧2 received data sequences received from respective N a ≧2 antennas; a signal generation unit configured to generate K>N a signal data sequences from the received data sequences; K>N a signal paths each configured to transmit one of the respective signal data sequences; a plurality of prefilter units, each coupled to one of the signal paths; and a combiner comprising K>N a input terminals that are each connected to an output terminal of one of the prefilter units, wherein the signal generation unit is configured to generate K 1 first signal data sequences, wherein each first signal data sequence is identical to one of the received data sequences, respectively, and K 2 second signal data sequences, wherein each second signal data sequence is not identical to any one of the received data sequences, respectively, and wherein K 1 +K 2 =K.
