| 摘 要： | 利用TD-SCDMA中上下行信道的对称性,提出一种在基站侧进行发送信号处理以实现空分多址的算法,并分析了其计算复杂度。该算法通过对空时二维信号的处理,发送空时二维信号构成一个矩阵,利用矩阵的零子空间以实现空分多址。该算法无需改变终端结构,在基站侧安装8根天线,就可以以适中的计算复杂度取得系统容量的数倍提高。

| Abstract: | By employing the symmetric property of the uplink and downlink channel,a transmit signal processing technique is proposed,which can lead to spatial division multiple access (SDMA) for time division-synchronous code division multiple access (TD-SCDMA). With space and time two dimensional signal,a matrix is constructed,and the null space of the matrix is utilized to realize SDMA. The complexity of this technigue is analyzed. Without any changes in the user equipment,this technique can increase the capacity se... |
