摘要 在时分双工(TDD)多输入单输出(MISO)系统中,发送机通过信道估计获得信道状态信息(CSI),根据信道互易性可用其计算发送波束成形(TBF)的加权向量。然而,由于信道估计和TDD的收发机时延,CSI可能会不准确。通过推导接收机误比特率(BER)与CSI的闭合表达关系,分析了不准确的CSI对接收机性能的影响。最后用数值仿真验证了性能分析的正确性。 In a Time Division Duplex (TDD) Multiple Input Single Output (MISO) system, the transmitter obtains channel state information (CSI) by channel estimation. Then the CSI can be used to generate weights of transmit beamforming (TBF) according to channel reciprocity. However, because of the channel estimation and the delay between the transmitter and the receiver, the CSI may be imperfect. In this paper, the closed-form expression of Bit Error Rate (BER) and CSI is derived to analyze the impact of imperfect CSI on performance of the receiver. Finally, the performance analysis is demonstrated through numerical simulations.
