Generalized Full/Partial Closed Loop Transmit Diversity Algorithm for WCDMA 2003 http://ezaposleni.singidunum.ac.rs/rest/sciNaucniRezultati/oai/record/2/3056 http://onlinelibrary.wiley.com/doi/10.1002/ett.931/abstract D. Novaković M. Juntti M. Dukić In this paper an algorithm for generalized transmit diversity is proposed. Depending on the signal-to-interference-plus-noise ratio maximization criterion full diversity (all available transmit antennas) or partial diversity (only subset of all available transmit antennas) is used and phase adjustment is applied between selected antennas. It is shown that the proposed algorithm offers a considerable gain in transmit signal-to-noise ratio per bit compared to all-antenna transmission and one-antenna selection transmit diversity. The gain is present for both uncorrelated fading and for correlated fading between transmit antennas. Furthermore, it has been shown that the proposed algorithm is more robust to the channel estimation errors. article 10.1002/ett.931 14 5 471 477 1124-318X EUROPEAN TRANSACTIONS ON TELECOMMUNICATIONS
