摘要 对于多发单收的天线系统(MISO),在已知信道状态信息(CSI)和等发射天线功率分配的情况下,利用反馈的CSI,对采用正交空时组码(STBC)的N选择n(N≥n,即n-NTx)的MISO系统进行研究。给出了求解选择性信道的序系数,推导了n-NTx系统的边缘概率密度函数(pdf)。在独立的平坦瑞利衰落信道中,完整地导出了n-NTx系统关于BPSK/QPSK调制的比特误码率(BER)性能界的理论表达式。为了与没有天线选择(即满复杂度)的系统进行性能比较,给出了BER的理论分析值和蒙特卡洛仿真结果,它们的结果均表明多天线选择系统能极大地提高系统的性能。 For a multiple input (MTx) single output (1 Rx) (MISO) communication system, the system in which orthogonal spacetime block coding (STBC) selection on n best transmit antennas out of N transmit antennas(N 〉 n, i. e. n-NTx) is adopted is studied by applying feedback channel state information (CS1) in the case of known CSI and equal transmit power allocation. The marginal probability density function (PDF) of n-NTx system is deduced and an approximate closed-form expression of Bit-Error Rate (BER) bound for BPSK/QPSK is derived in detail over the uncorrelated Rayleigh fading channels. In order to compare with the performance of the system without n-NTxs, the analytical results and computer Monte-Carlo simulation results of BER for BPSK/ QPSK modulation are also presented. Some suggestions are given for reducing BER and increasing transmission capacity.
