Quadrature Amplitude Modulation and Demodulation Techniques

Mr. Jitendra Kumar Saroj, Ms. Meenakshi Sharma.

Abstract
Quadrature Amplitude Modulation (QAM) modulation scheme is considered as a significant digital
communication network that utilizes complex calculations to perform vast structures. The technique utilizes power
to perform the same. The paper utilizes low power as it uses reversible logic gates as a method of balanced result
between the input and output. The paper focuses on the systematic approach of the different demodulation and
modulation technique. The fundamental approach includes the presence of some amount of Gaussian noise. The
inaccuracy in calculating the probability of error has been analysed. The interference occurring in demodulator
has also been analysed. QAM modulators are digitally analysed using “Verilog HDL” coding and “RTL compiler”
that contains a pre-defined library hub. A decreased power utilization has been used in regulating the QAM
modulation technique. QAM demodulator is presented that has none of the drawbacks referenced above and that
can be productively executed by methods for present day PLDs.

Key words: Noise, Phase Locking, PLDs, QAM, Signal processing.
