Adaptive Array Measurements in Communications

by M.A. Halim

Overview

One of the most damaging factors associated with any radio communication system is the effect of undesirable or interference signals. This innovative new book gives you the knowledge you need to ensure your adaptive array system is protecting your communication links to the fullest. It presents concepts and procedures that help you realize the maximum processing capabilities of a given system, choose the right system for a specific application, and identify precautionary steps to avoid adverse effects.

Editorial Reviews

Intended for students at post-secondary levels, this book leaves aside most of the mathematical analysis and provides a general overview of the principles of operation (it assumes an active array system is already available). Halim, an engineer with a private company, calculates the theoretical capabilities of the system to remove the interference signals under various operating conditions; presents simpler forms of the complex mathematical expressions involving matrix and vector algebra found in related textbooks; and discusses some key devices and subsystems used in the construction of an adaptive array.
