Additionally, the carrier loop noise bandwidth and the correlator spacing are reduced. Then the accuracy of carrier and code tracking loops is improved significantly.

同时，降低载波环噪声带宽，减小码环相关间隔，从而提高了载波环和码环的跟踪精度。

Many existing CO DSL modems may only support a relatively narrow receive frequency range, which will increase the difficulty of estimating the much wider bandwidth far-end loop noise.

许多已有的CO(中心局)dsl调制解调器可以只支持相对较窄的接收频率范围，这会增加估计宽的多的远端环路噪声的难度。

As the offending noise continued in a loop, Mr. Gilbert turned in its direction and pointedly asked that the phone be turned off.

The firm maintains that it had been pitching its patented noise cancellation to Apple in periodic meetings between 2007 and 2010, only to watch as 1 Infinite Loop used Audience's technology for the iPhone 4 instead -- and supposedly handed some of Noise Free's work to a competitor.
