In a cellular system, there is full duplex communication, between a base station and a mobile. The two directions are called either uplink (from mobile to base station) or downlink (from BS to mobile). The downlink channel is synonymous with “forward channel”; the uplink channel is synonymous with the “reverse channel”.

ECE 5520: Digital Communications Lecture Notes Fall 2009

my.ece.utah.edu

A digital communication system conveys discrete-time, discrete-valued information across a physical channel. Information sources might include audio, video, text, or data. They might be continuous-time (analog) signals (audio, images) and even 1-D or 2-D. Or, they may already be digital (discrete-time, discrete-valued). Our

2.0 Root Locus Design Consider all positive values of k. In the limit as k -> 0, the poles of the closed-loop system are a(s) = 0 or the poles of H(s). In the limit as k -> infinity, the poles of the closed-loop system are b(s) = 0 or the zeros of H(s). No matter what we pick k to be, the closed-loop system must always have n poles, where n is the
