针对RAKE接收机在接收信号时抽头系数估计有误差的情况,研究了在高斯噪声与抽头系数误差不独立时,在相关Nakagami信道下的接收的性能。给出了在相关衰落情况下,误码率的闭合计算式。数值结果表明,与具有精确估计接收机相比,具有估计误差时,相关性对接收机的性能造成更大的影响。 Aiming at the error of the RAKE receiver when the received signal is estimated, the receiver performance under correlated Nakagami channel is studied when the Gaussian noise and tap coefficient error are not independent. The closed-form formula for bit error rate is given under the condition of relative fading. Numerical results show that the correlation has a greater impact on the performance of the receiver when there is an estimation error than with an accurately estimated receiver.
