数字信号相乘，由于伪随机码速率快，扩展了传输带宽（伪随机码带宽远大于信号带宽，扩展信号频谱），在接收端，用相同的伪随机码序列
The Do the job Strategy can be a desk which contains all of the deliverables becoming worked on, with the most recent WIDs and SIDs at the very best with the system and before products detailed at the bottom.
It’s gotta be quite possibly the most cost-effective!” Even though USPS has a fantastic shipping and delivery network and cost-effective services which might be hard to beat, it doesn’t usually offer you the ideal rates.

是利用电磁波的反射特性来探测目标。雷达发射机产生特定频率、波形的电磁波，经由天线向空间定向辐射，形成具有一定方向性的波束。当波束遇到目标物体时，电磁波会在目标表面发生反射，其中部分反射波沿着原路返回被雷达天线接收，接收机对微弱的回波信号进行放大、滤波、解调等一系列精细处理，提取出目标的距离、方位、速度等关键信息。这一过程如同向黑暗中投掷石子，通过聆听回声来判断周围物体的位置
Sorts of Multiplexing in Data Communications Imagine you might have a number of close friends who all choose to ship letters to the same particular person check here concurrently.

В явном виде отсутствует временное или частотное разделение каналов, каждый абонент постоянно использует всю ширину канала, передавая сигнал в общий частотный диапазон и принимая сигнал из общего частотного диапазона. При этом широкополосные каналы приёма и передачи находятся на разных частотных диапазонах и не мешают друг другу.
