ECE 5325/6325: Wireless Communication SystemsLecture Notes, Fall 2011 Prof. Neal PatwariUniversity of UtahDepartment of Electrical and Computer Engineeringc 2011 ECE 5325/6325 Fall 20112 Contents1 Cellular Systems Generation Zero .. Cellular .. Key Terms .. 72 Frequency Transmit Power Limits .. Cellular Geometry .. Channel Assignment within Group .. Large-scale Path Loss .. Co-Channel Interference .. Downtilt .. Handoff .. Review from Lecture 2 .. Adjacent Channel Interference.

The study of the history of cellular systems can help us understand the need for the system design concepts we have today. One of the major developments in WWII was the miniaturization of FM radio components to a backpack or handheld device (the walkie-talkie), a half-duplex (either transmit or receive, not both) push-to-talk communication device.

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
