This scheme can effectively mitigate interference of other users, and minimize the total transmit power under the constraint that all the users achieve the requisition of Signal-to-Interference Ratio ( SIR), also the convergence of the SIRs to the common target SIR rapidly. 该方案能更加有效地消除干扰信号,同时在满足信干比(SIR)要求时,所有用户发射总功率最小,收敛速度最快。

After the received signal vectors are sent into the conventional matched filter, the sample vectors that maximize signal-to-interference ratio at the output of the filter are collected, and optimally combined across both space and time. 在接收信号矢量经过传统的匹配滤波器后,按照最大信干比准则选取输出矢量样本,并进行最优化空时二维合并。
In cellular mobile communication networks, the actual coverage region is the area where the received signal power and signal-to-interference and noise ratio ( SINR) of the common control signals are higher than the preset thresholds respectively. 在蜂窝移动通信网络中,公共控制信号强度、信干噪比均不低于门限的区域构成了小区的实际覆盖范围。
