Abstract

Devices and methods for suppressing interference in inter-cell and intra-cell network communication. First and second received signals are received at a communication device, the first and second received signals comprising, respectively, reference signals and data signals. Estimated channel vectors are calculated from the first received signals, and estimated data covariance matrices are calculated from the second received signals. A plurality of combining weight vectors are determined based on the estimated channel vectors and the estimated data covariance matrices. The second received signals are then combined with the plurality of combining weight vectors to obtain a plurality of combined signals, wherein interference in the second received signals has been suppressed in the plurality of combined signals.
