Fundamentals of Quadrature Amplitude Modulation

Laboratory home page

Aim of the Experiment

This experiment primarily concerns the design and implementation of a Quadrature Amplitude Modulation (QAM) transmitter. QAM is a widely used method of transmitting digital data over bandpass channels. QAM is a popular choice because of its bandwidth efficiency and its ability to compensate for linear channel distortion.

Before you start with the experiment, it is necessary that you have an understanding at some level of the following concepts:
