摘要 在多径衰落环境中,MIMO系统的信道容量随天线数的增加呈线性增加,发射/接收天线选择方法能以很小的性能损失换取射频成本的大幅度降低,使MIMO系统不完全受射频成本的限制。为快速选择出使系统容量最优的发射/接收天线子集,该文提出一种快速天线选择算法的改进算法。该算法通过实时更新优化参数,大大降低计算复杂度。仿真结果表明,该算法在不影响系统容量的情况下大大减少了计算时间。 The capacity of MIMO system is increased linearly with the number of the antennas in multi-path fading environments, and transmit/receive antenna selection barters little lost of system performance for great decreasing of RF cost, making MIMO system not fully limited by RF cost. To quickly select transmit/receiver antenna subset making the system capacity best, this paper proposes an adapted algorithm for the fast antenna selection algorithm, which reduces the computation complexity by updating the quantities in real time. Simulation results indicate that the algorithm decreases computation time a lot without any system capacity lost.
