| 摘 要： | 研究了蜂窝通信系统中基站同时与N个移动用户通信时一种新的发送分集方法。该方法将N个用户的信源信号在发送端采用线性变换进行联合编码后送入N个独立信道进行传送。分集发送信号经衰落信道传送后，对每一个信号接收者，其收到的信号可以表示成格型码的形式，可以使用球型译码算法进行信号解调

| 关 键 词： | 发送分集 多用户分集 球型译码 衰落信道 |

| Abstract: | A new transmit diversity for a cellular system that a base station simultaneously communicates with N users is studied. Signals from the N users are encoded jointly using a linear transform and then transmitted with N independent channels. The received signal at a particular destination can be represented as lattice form and detected with sphere decoding algorithm. |

| Keywords: | transmit diversity multi-user diversity sphere decoding fading channel |
