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 integrate-and-dump detector is fundamental to coherent detection, the optimal receiver technique that minimizes bit error rate (BER) for a given signal-to-noise ratio Eb/No. In this project develop a pulse amplitude (PAM) transmitter based on a transmit filter to map a bitstream onto a signaling waveform (rectangular and Manchester pulse shapes), an additive white Gaussian noise (AWGN) channel, and a receiver that implements integrate-and-dump detection. All waveforms throughout the signal processing chain are presented as a stacked chart indicator with a speed control to permit generated waveforms to be studied slowly (i.e., the integrator output ramping up or down) or quickly to process long message bitstreams. Visualizing the critical system signals as waveforms facilitates exploration of the effects of specific values of BER and Eb/No, and promotes deeper understanding of coherent detection. Less
