本文首先提出了客观评价噪声压缩效果的两个指标：残余噪声能量和信号畸变指标。
This paper firstly presents two criteria: residual noise energy and signal distortion criterion to evaluate the degrees of noise suppression and signal distortion.
限幅法是目前应用较为广泛的一类预畸变峰均比抑制算法，但其会引入额外的限幅噪声，从而对数据信号和导引符号造成干扰，恶化传输性能。
Clipping is a popular method to control the PAPR with distortions, but it introduces additional clipping noise, so as to distort the data and pilot symbols and degrade the system performance.
