Exploring QAM using LabView Simulation (m14499)
Keywords: LabView, QAM, Quadrature Amplitude Modulation, Simulation
Summary: 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 ... pulse shaping.

Quadrature Amplitude Modulation (QAM) Experiments Using the National Instruments PXI-based Vector Signal Analyzer (m14500)
Keywords: 3D Eye Diagram, LabView, National Instruments PXI, QAM, Vector Signal Analyzer
Summary: 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 ... signals work.

Interactive Ball and Beam Experiment (m14028)
Author: Erik Luther
Summary: The ball and beam experiment represents a simple second order system. This system is easily simulated using four states, but is more difficult to implement in real-life because not all necessary variables are easily observed. This simulation assumes all four states are easily observed and the system is linear ... Simulation Module.

Texting Over the Speaker-Air-Microphone (SAM) Channel (m18670)
Author: Ed Doering
Keywords: amplitude shift keying, ASK, bitstream regeneration, bit synchronizer, envelope detector, frame synchronization, LabVIEW, preamble, receiver, receiver filter, speaker-air-microphone channel, text messaging, transmitter
Summary: Texting and instant messaging are familiar and popular communication techniques. Text messages composed of ASCII characters, with each character composed of eight bits, ultimately form a stream of bits transmitted from the source to the receiver. Normally the text message moves through a complex data network, and the user only ... ASK receiver.

PAM Transmitter and Receiver Implementing Coherent Detection (m18652)
Author: Ed Doering
Keywords: additive white Gaussian noise, AWGN, BER, bit error rate, coherent detection, correlator, Eb/No, integrate-and-dump, LabVIEW, PAM, point-by-point processing, pulse amplitude modulation, signal point mapper, signal to noise ratio, stacked chart, transmit filter
Summary: 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 ... coherent detection.
