| 摘 要： | 在MIMO系统中天线选择可以增加系统容量,并能有效地降低MIMO系统的复杂度和射频成本。在对天线选择算法研究的基础上,设计了一种新的基于范数和行向量相关的快速算法获得较大的信道容量。该算法没有矩阵运算,计算复杂度低。最后通过仿真分析与其它算法进行了比较,表明该算法在接收天线数和发送天线数不相等时和最优算法基本一致,优于其他算法。

| Abstract: | Antenna selection can increase channel capacity in MIMO system,and can also effectively decrease the system complexity and the Radio frequency cost.Antenna selection algorithms are discussed,and a new fast algorithm is proposed based on norm and correlation of row vectors,which gets more channel capacity and has low complexity because of avoiding matrix operation.At last simulation analysis and comparisons indicates that the new algorithm is almost near to the optimum one,much better than others,when receiving antenna number is not equal to transmitting's. |
