在这封信中，我们使用等增益传输 (EGT) 预编码推导了多用户多输入多输出 (MU-MIMO) 系统的误码率 (BER) 性能。考虑到二进制相移键控（BPSK）调制，我们分析并提出了一种基于 Nakagami 分布的统计模型，用于接收信号中涉及的干扰项。我们的模型的精度与常见的高斯近似进行了比较，并通过仿真结果进行了验证。对于任意 Eb/N0，封闭式 BER 表达式是作为发射天线数量的函数导出的。
In this letter, we derive the bit error rate (BER) performance of a multiuser multiple-input multiple-output (MU-MIMO) system using equal gain transmission (EGT) precoding. Considering binary phase shift keying (BPSK) modulation, we analyze and propose a statistical model based on the Nakagami distribution for the interference terms involved in the received signals. The precision of our model is compared with the common Gaussian approximation and validated through simulation results. A closed-form BER expression is derived as a function of the number of transmit antennas for arbitrary Eb/N0.
