WebThe difference is pretty quickly explained: the CTFT is for continuous-time signals, i.e., for functions x(t) with a continuous variable t ∈ R, whereas the DTFT is for discrete-time signals, i.e., for sequences x[n] with n ∈ Z. That's why the CTFT is defined by an integral and the DTFT is defined by a sum: X(jΩ) = ∫∞ − ∞x(t)e − jΩtdt Web前言. 本文主要介绍通信系统中有关信道的两个非常重要的参数:相干时间与相干带宽 一、相干时间 (Coherence Time) 无线通信系统的信道非常复杂,所面临的环境包含了直射,反射,绕射,衍射,散射,相干,阴影等由障碍物所引起的一系列复杂的信道,这对信号的在空间中的传输造成了很大的影响 ...
