摘要 文中研究了混合发射天线选择的等增益传输(TAS-EGT)系统优化设计问题。根据信道衰落系数的排序统计特性,给出了TAS-EGT系统的平均接收信噪比,提出了最小发射天线数的计算方法。由于TAS-EGT系统的性能并非完全正比于射频链路数,因此文中提出了最优射频链路数的计算方法。仿真结果显示增加少量的发射天线可以节省大量的射频链路。因此,文中提出的算法可以降低系统的成本和复杂度,优化系统的性能以减少不必要的开销。 This paper investigates the optimization of equal gain transmission systems with transmit antenna selection. According to statistic ranking of wireless channel fading coefficients, a formula of average SNR calculation for TAS-EGT systems is deduced and furthermore an algorithm to determine transmit antennas number is proposed. Since the performance of TAS-EGT systems is not all proportional to RF chains number, an optimizing algorithm of RF chains number is presented. Simulation results show that only a few...
