分析了循环前缀单载波在多用户干扰下的传输性能。对于使用单载波频域自适应天线阵列的多用户接收机，通过分析频域到时域变换后的时域估计信号，推导出信噪比。假设MUI服从高斯分布，我们可以推导出误码率性能的解析表达式。用蒙特卡罗方法生成的数值结果验证了分析结果。分析结果表明，在大规模多输入多输出（massive multiple multiple output， MIMO）系统中，如果假设接收天线数量趋于无穷大，则误码率性能将由信噪比和信噪比两个比值决定。信噪比为接收天线数量，信噪比为用户数量。
This paper analyzes the performance of cyclic prefixed single-carrier transmission under multiuser interference (MUI). For multi-user receivers using single carrier frequency domain adaptive antenna array, we derive the signal to interference plus noise ratio by analyzing the time domain estimated signal after the transformation from frequency domain to time domain. By assuming the MUI follows the Gaussian distribution, we can derive the analytical expression for the bit error rate (BER) performance. The analytical result is verified by the numerical results generated by Monte Carlo method. It is concluded from the analytical results that if the number of receive antennas goes to infinity as assumed in massive multiple input multiple output (MIMO) system, the BER performance will be determined by two ratios: signal to noise ratio as well as theNrtoUratio, whereNris the number of receive antennas andUis the number of users.
