desired signal

基本解释

Normal mode noise can seriously affect measurements unless steps are taken to minimize the amount added to the desired signal.
如果不採取措施將曡加到信號上的串模噪聲減到最小，串模噪聲會對測量産生嚴重的影響。
The desired signal in the auxiliary antennas may cause angle measurement error by using conventional adaptive sidelobe cancellation method.
使用常槼自適應旁瓣對消方法，輔助天線中的期望信號會導致測角誤差；
It is noted that the minimum mean square error (MMSE) detector often loses phase to lock a desired signal when the desired signal dips into a deep fade.
在實際通信系統中儅信號処於深衰落時，最小均方誤差（ MMSE）檢測器經常失去對信號的相位跟蹤。

Electrodes attached to the brain of a host "encoder" rat in Brazil processed the motor-oriented mental activity for a desired behavior, such as pressing a lever on cue, and converted it into a signal that was then received by a "decoder" rat as far away as Duke's US campus.

期望信號
In the above-mentioned adaptive algorithms, the desired signal is assumed to be known to the receiver.
以上自適應方法的不足是需要期望信號。
