一种应用小数编码GA算法的MIMO天线选择方法

针对多输入多输出（MIMO）技术传统遗传算法（GA）的天线选择在进行遗传运算操作时,会遇到二进制染色体编码与选择天线数不匹配的问题,提出了一种用小数编码的GA遗传算法用于MIMO天线选择,所提方法可以有效解决传统GA在遗传操作上的问题,并具有较低的复杂度。

A DECIMAL CODED GA ALGORITHM IN ANTENNA SELECTION OF MIMO SYSTEM

Multiple-input multiple-output（MIMO） technology uses multiple transmit antennas and multiple receiving antennas to exponentially increase the channel capacity and spectrum utilization.Antenna selection is to select the transmit/receive the originator of the transmission signal better antenna for transmit/receive signals,thus reducing the hardware cost of the system.With the computational complexity is low,real-time to good advantage,but during the operation of the genetic operators,the experience does not match the binary chromosome encoding and select the number of antennas,this paper proposes a traditional antenna based on genetic algorithm（GA） to select using decimal encoding GA antenna selection algorithms.The proposed method can effectively solve the problem of the traditional GA on the genetic manipulation,and has the same low complexity.
