Principles of Communication Systems Simulation with Wireless Applications

Chapter 5. Filter Models and Simulation Techniques

This chapter focuses on the development of simulation models for filters. Filters are an important part of many of the subsystems that make up a communication system. Many of these filters are analog and must be mapped to a suitable digital equivalent for simulation purposes. A number of techniques are available for performing this mapping, all of which involve approximations and all of which induce errors in the simulation results. The technique used for generating a given filter for use in a given application will depend on a number of factors. Many of the most useful techniques for synthesizing and simulating filters will be explored in this chapter. Of particular interest are the limitations ...
