Summary: Wireless Communication Systems Lab-Manual-4
Digital Modulation Techniques
The objective of this experiment is to understand the various Digital
Modulation Techniques and observe the related modulation quality
measurements. The students will be familiar with the following items:
o Various modulation Types.
- Constant envelope versus higher order
- Understanding power, spectral efficiency, and data
- Comparisons of various modulation types in terms
of: time envelope, spectral efficiency, EVM
performance, constellation, and eye diagrams.
o The tradeoff between higher data rates and higher
susceptibility to noise at higher orders of modulation (like
64QAM) Overall capacity increase or decrease at higher
o Understanding CCDF
