摘　　要：用矢量范数定义了一类多发射天线系统,并对各系统的中断概率性能进行了研究。分析表明,虽然各种多发射天线方法根据其接收机和发射机所获得的信道信息不同,采用不同的功率分配算法和发射编码准则,但其中断概率随信噪比的增加呈现相似的渐进性能。A class of multiple transmit antenna systems is defined based on vector norm and the outage probability of them are studied. The result shows that although their channel side information are different at transmitter and receiver, as well as power allocation and coding, the decreasing of the outage probability of multiple transmit antenna systems is similar when signal to noise ratio is creased.

关 键 词：多发射天线 矢量范数 中断概率
