TOPIC: “A QAM BASED COMMUNICATION SYSTEM”

ABSTRACT:
This project involves design of a communication system which includes Quadrature Amplitude modulation (QAM) technique. The system’s modules which condition the signal are an Elliptical Bandpass analog Filter, a Butterworth Lowpass Analog Filter, an Analog to Digital Converter and a Digital to Analog Converter. A basic explanation of all the modules is stated along with the advantages and disadvantages of the respective designs. Multisim designs for filters, Analog to Digital Converters & Digital and Analog Converters are developed. The simulated waveforms, AC Analysis, DC Analysis of the Filters, Analog to Digital Converters and Digital to Analog Converters are shown.

Quadrature Amplitude Modulation & Demodulation Modules are coded using Verilog and the code is synthesized using Questasim. Critical Path delays for the modulator and demodulator sections are calculated.

NOTE: All ECE Graduate Students are ENCOURAGED to attend.
All interested parties are invited to attend.
Open to the public.
