Communications Toolbox

Using the Communications Toolbox

A typical communication system includes a signal source, sink, and channel, as well as processes for transmitting and receiving. This chapter describes and illustrates how to implement communication components using the functions provided in the Communications Toolbox. Each section in this chapter corresponds to a category of functionality within the Communications Toolbox. The sections are as follows.

Random Signals and Error Analysis	Random signals, error rates, eye diagrams, and scatter plots
Source Coding	Scalar quantization, differential pulse code modulation, and companding
Block Coding	Creation and decoding of block codes
Convolutional Coding	Creating and decoding of convolutional codes
Modulation	Analog and digital modulation
Special Filters	Raised cosine filters and Hilbert transform filters
Galois Field Computations	Computations in a Galois field having an even number of elements
