- Abstract:
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.

- Abstract:
Huffman variable length source coder is first described then systematic channel coding block coder design is introduced for forward error correction coding (FECC). Nearest neighbour decoding and the Hamming bound is used to define the performance of these block coders. Finally the nonsystematic convolutional coder, Viterbi decoder and turbo recursive coder designs are introduced with examples of the operation of these coders.
