Introduction

Matlab is an ideal tool for simulating digital communications systems, thanks to

its easy scr ipting language and excellent data visualization capabilities. One of the

most frequent simulation tasks in the field of digital communications is bit-error-

rate testing of modems. The bit-error-rate performance of a receiver is a figure of

merit that allows different designs to be compared in a fair manner. Performing

bit-error-rate testing withMatlab is very simple, but does require some prerequisite

knowledge.
