The OFDM system has a major disadvantage that high peak to average power ratio (PAPR) can cause nonlinear distortion in the high power amplifier (HPA).
OFDM系统的一个主要缺陷就是峰平比过高引起的高功率放大器(HPA)的非线性失真。
The result shows that this method can get rid of the short-circuit peak pulse nicely, and the waveform distortion is really small.
结果表明，该方法很好地滤除短路尖峰脉冲，波形失真甚小。
There are two disadvantages in adaptive beam forming in the presence of main lobe interference, one is heightening of side-lobe level, the other is distortion and peak offset of main beam.
在自适应波束形成技术抑制干扰问题中，当存在主瓣干扰时，便暴露出两个缺陷：一是副瓣电平增高；
