[求助] 求助英文語(yǔ)法錯(cuò)誤

請(qǐng)高手指點(diǎn)下面三個(gè)英文句子的表達(dá)或者語(yǔ)法錯(cuò)誤。已標(biāo)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：該方法使用從兩個(gè)不同延時(shí)反饋回路反饋回來(lái)的數(shù)據(jù)，來(lái)分離并估計(jì)誤差）

“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.” （傳輸這樣高峰均比的信號(hào)經(jīng)過(guò)PA，會(huì)導(dǎo)致頻譜再生和誤碼率的降低，所以在現(xiàn)代無(wú)線通信系統(tǒng)中，高線性度的PA是必須的）

“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”,（從（12）（13）可以看出：這些常數(shù)都是關(guān)于輸入復(fù)信號(hào)的線性函數(shù)，并且他們可以通過(guò)3個(gè)輸入和反饋信號(hào)的采樣點(diǎn)來(lái)求解。）

愛(ài)與雨下(金幣+1): 呵呵！~ 2011-08-22 12:09:19
zhanp324(金幣+30, 翻譯EPI+1): 非常感謝，看來(lái)第一個(gè)句子的問(wèn)題不是簡(jiǎn)單的語(yǔ)法錯(cuò)誤 2011-08-22 14:48:02

第一句沒(méi)什么問(wèn)題

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”
