[求助] 求助英文语法错误

请高手指点下面三个英文句子的表达或者语法错误。已标注大概的中文意思。

“It uses the captured signals, which transmit through two different propagation delay feedback loops, to separate and estimate the errors.”(it 指上文提到的方法,中文意思:该方法使用从两个不同延时反馈回路反馈回来的数据,来分离并估计误差)

“Transmitting such high peak-to-average power ratio (PAPR) signals through nonlinear PA result in spectral regrowth and degradation of the bit error rate, so the high linearity PA are necessary in modern wireless communication systems.” (传输这样高峰均比的信号经过PA,会导致频谱再生和误码率的降低,所以在现代无线通信系统中,高线性度的PA是必须的)

“From (12) and (13) we can see that those constants are linear functions about the input complex signals, and they can be solved by using only three samples of the input and feedback complex signals”,(从(12)(13)可以看出:这些常数都是关于输入复信号的线性函数,并且他们可以通过3个输入和反馈信号的采样点来求解。)

zhanp324(金币+30, 翻译EPI+1): 非常感谢,看来第一个句子的问题不是简单的语法错误 2011-08-22 14:48:02
第一句没什么问题

第二句:Transmitting such high peak-to-average power ratio (PAPR) signals through nonlinear PA results in spectral regrowth and degradation of the bit error rate, which means that the high linearity PA is necessary in modern wireless communication systems.”

第三句:“From (12) and (13) we can see that those constants are linear functions about input complex signals, which can be solved by three samples of the input and feedback complex signals”
