Abstract For Space-Time Block Code (STBC) systems with unknown co-channel interference in multi-cell environment, focusing on the problem that the Capon-style receivers will result the self-interference in the STBC codeword from the finite samples, a robust linear receiver is proposed. Based on the orthogonal structure of the STBC, the self-interference in the STBC codeword is first canceled with the orthogonal projection. Then Capon receiver is used to suppress the unknown interference. Simulation results are presented to demonstrate the significant gain obtained by the proposed linear receivers over the conventional Capon receiver.
