In this project, develop a simple model for a transmitter, channel, and receiver, and study the performance of the system in terms of bit error rate (BER). Channel errors are visualized as images and "auralized" as sound to further develop insight into the relationships between bit error rate and message length.

This module explores the topic of Quadrature Amplitude Modulation (QAM) through the use of National Instrument’s LabView Modulation Toolkit. The QAM Transceiver simulation tool provides an excellent tool for learning about the most important aspects of QAM. This module first reviews basic theory of QAM, and then presents a series of simple exercises designed to introduce the reader to basic concepts such as noise, bandwidth, and pulse shaping.

This module discusses the use of National Instruments PXI system for understanding QAM signal transmission. The PXI system discussed here has been configured as a software-defined transmitter/receiver system and is used to implement both a spectrum analyzer and a vector signal analyzer under LabView control. It is thus extremely well suited for studying and learning how QAM signals work.

The telephone company's "Caller ID" service provides the calling party's directory information as well as the time and date of the call as an FSK (frequency shift keying) signal between the first and second rings of a telephone call. In this project, develop a complete Caller ID decoder that analyzes an audio recording of the FSK signal to extract the directory and date information for display.

The LabVIEW Modulation Toolkit is an optional add-on to LabVIEW that offers a wide variety of subVIs to quickly and efficiently implement digital and analog communication systems. Many different modulation schemes are supported (PAM, ASK, PSK, FSK, QAM, CPM, and MSK), as are channel impairment models, channel coding, and visualizations such as constellation plots, eye diagrams, and trellis diagrams. This module introduces the toolkit with several demonstrations, and shows how to re-implement existing LabVIEW communication systems projects with the toolkit.

"Communication Systems Projects with LabVIEW" features ten projects that draw upon a library of over 40 subVIs constructed as part of the project activities. Each module in this manual completely describes the input/output requirements as well as the required behavior of a subVI. In addition, each module features a narrated screencast video of the LabVIEW program in action to demonstrate relevant coding techniques to successfully build and test the subVI. Use the Connexions "Table of Contents" viewer to quickly browse for subVIs of interest. Download the manual as a single PDF document (see "Content Actions") as a convenient way to access all modules in a single file; the PDF includes an index.
