Abstract

This paper proposes 4-STTD(4${\times}$l) technique for the shake of application of W-CDMA which expand Alamouti STTD(2${\times}$l) technique. As the result of analyzing 4-STTD(4${\times}$l) technique proposed in this paper, we can see improvement of quality by approximately 2.2 dB rather than Alamouti STTD(2${\times}$l) technique
