The purpose of this activity is to introduce students to the concept of binary coding as a language and its practical applications in digital and communication systems. This project is intended to give students a deeper appreciation for communication systems and an understanding of how binary symbols are used to transmit information.

Communication Systems Projects with LabVIEW features ten project activities in digital communication systems based on the LabVIEW graphical dataflow programming platform. Each project includes introductory material in the form of text and narrated screencast videos, specifications for low-level subVI building blocks, and step-by-step instructions to assemble application VIs to implement a variety of simulations, visualizations, and working transmitters and receivers. This textbook organizes the projects into related topics, including: (1) Simulation and Visualization of Fundamental Concepts, (2) Channel Coding and Error Control, (3) FSK Demodulation (Caller ID), and (4) Bandpass Communications over the Speaker-Air-Microphone Channel.

The following section describes the receiver end of the string can telephone setup.

This module describes a decision procedure for decoding received signals. The implementation and analysis of a correlation receiver is included.

Bit streams through digital communications receivers.

Simulation and visualization enhance understanding of communication system behavior and performance. 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.

The goal of symbol-timing recovery is to sample message signals at the receiver for best performance. After the in-phase and quadrature signals pass through a matched filter, a delay-locked loop attempts to find the peaks in the output waveforms.

Examples of the use of a correlator-type receiver

Students are introduced to various types of hearing impairments and the types of biomedical devices that engineers have designed to aid people with this physical disability.

For thousands of years, navigators have looked to the sky for direction. Today, celestial navigation has simply switched from using natural objects to human-created satellites. A constellation of satellites, called the Global Positioning System, and hand-held receivers allow for very accurate navigation. In this lesson, students investigate the fundamental concepts of GPS technology trilateration and using the speed of light to calculate distances.

A performance analysis of correlator-type and matched filter receivers on binary symbol transmission using both orthogonal and antipodal signal sets. Both types of receivers perform identically with the same detection criteria.

Bit-error analysis for an antipodal signal set by using a correlator-type receiver.

Bit-error analysis for an antipodal signal set by using a matched filter receiver.

Detection and measurement of radio and optical signals encountered in communications, astronomy, remote sensing, instrumentation, and radar. Statistical analysis of signal processing systems, including radiometers, spectrometers, interferometers, and digital correlation systems. Matched filters and ambiguity functions. Communications channel performance. Measurement of random electromagnetic fields. Angular filtering properties of antennas, interferometers, and aperture synthesis systems. Radiative transfer and parameter estimation.

NBC's Lester Holt looks at the role vectors play every time an NFL quarterback throws a pass. With the help of former NFL quarterback Joey Harrington, NSF-funded scientist John Ziegert of Clemson University and NSF-funded mathematician Rhonda Hughes of Bryn Mawr College explain how to use vectors to calculate the speed and direction needed for a completed pass.

This is a simple activity to visualize a communication system. In order to do this the students encode, decode, transmit, receive and store messages. They will use a code sheet and flashlight for this process. They will also maintain a storage sheet from which they can retrieve information as and when it is required.

An introduction to the fundamental model of communication, from the generation of the signal at the source through a noisy channel to reception of the signal at the sink.
