The number of antennas remains low, however, in current systems. For example, first-generation mobile WiMAX systems only employ two transmit antennas and the transmission scheme is based on either the Alamouti code or pure spatial multiplexing. For future generations, there is a strong interest both in more sophisticated space-time codes and higher number of antennas. With two transmit antennas, the best known full-rate code is the Golden code, which leads to a coding gain of 3.2 for all QAM signal constellations. But this code has a high decoding complexity, which grows with the 4th power of the number of points in the signal constellation. This has motivated research to develop space-time codes of lower decoding complexity, and several space-time codes were recently developed whose maximum-likelihood decoding complexity grows only quadratically with the size of the signal constellation. In the talk, we will review the space-time codes used in current wireless systems and summarize the results of research towards fast maximum-likelihood decodable space-time codes. The presentation will focus on 2x2 and 4x4 space-time codes. 主讲人简介：Hikmet Sari is Professor and Head of the Telecommunications Department at SUPELEC, which is one of the leading graduate schools in France in the field of Electrical Engineering. Since December 2004, he has also been Chief Scientist of SEQUANS Communications, a Paris-based start-up, which has become one of the leading providers of system-on-chip solutions for WiMAX. Previously, he held scientific and key management positions at Philips, SAT (SAGEM Group), Alcatel, Pacific Broadband Communication and Juniper Networks.（详细内容请见附件）此报告为前沿技术讲座（可以盖章），欢迎全校师生踊跃参加。
