Y (n) added three real sinusoidal signal f1 ' = 0.1, f2' = 0.25, f3 ' = 0.26 and sine signal amplitude adjustment signal to noise ratio is approximately 10dB, 50dB, 50dB. (1) that N = 256, depicted xn waveform (2) the true power spectral density obtained.

无线通信系统中信道仿真（包括AWGN信道，瑞利衰落信道，频率选择性衰落信道）(For channel simulation of wireless communication systems (including AWGN, Rayleigh fading channel, frequency selective fading channel))

In this letter, we derive a minimum mean squared error (MMSE) optimal estimator for clean speech spectral am-plitudes, which we apply in single channel speech enhancement. As opposed to state-of-the-art estimators, theoptimal estimator is derived for a given clean speech spectral phase. We show that the phase contains additional information that can be exploited to distinguish outliers in the noise from the target signal.
