Communications Toolbox

Studying Components of a Communication System

The Communications Toolbox implements a variety of communications-related tasks. Many of the functions in the toolbox perform computations associated with a particular component of a communication system, such as a demodulator or equalizer. Other functions are designed for visualization or analysis.

While the later chapters of this document discuss various toolbox features in more depth, this section builds an example step by step to give you a first look at the toolbox. This section also shows how tools in the Communications Toolbox build upon the computational and visualization tools in the underlying MATLAB environment. The topics are as follows:

• Modulating a Random Signal

• Plotting Signal Constellations

• Pulse Shaping Using a Raised Cosine Filter

• Using a Convolutional Code
