摘要 总结了差分酉空时调制的原理和编译码方法。差分酉空时调制是多输入多输出(MIMO)无线通信中不需要信道信息的一种调制方法,它的性能比相干检测接收差3dB。文中首先介绍了酉空时调制的基本原理和在各种信噪比下的信号星座图的设计原则;然后在此基础上介绍了不需要信道信息的差分酉空时调制;最后介绍了差分酉空时调制的最新进展,指出了其研究方向。 This paper summarizes the principle, coding and decoding of Differential Unitary Space-Time Coding （DUSTC）. DUSTC is a modulation for the MIMO when the channel state information （CSI） is absent. The performance of DUSTC is degraded 3dB as compared to the coherent receiver the design criterion for the signal constellations under the the DUSTC demanding no CSI. Finally, this paper points out the of the DUSTC This paper first presents the basic principle and different Signal-Noise Ratio, and then describes recent advancements and the development direction
