Summary: Wireless Communication Systems Laboratory #5
Filter Effect in Communication System
Objective
The objective of this experiment is to understand various Pulse Shaping
techniques and related measurements. The students will be familiar with the
following items:
a. Nyquist, raised cosine, ISI free filtering. Alpha factor, Time BW
relations.
b. Gaussian pulse shaping, ISI issues. Comparison of Gaussian, w.r.t.
Nyquist.
c. Study of various filters and their effect on the system, like spectrum
shaping: CCDF and PAPR effects, EVM and BER effects, inter-
symbol interference and eye diagram effects, vector (polar)
diagram, etc.
d. Discuss and simulate the effect of optimal match filtering under
AWGN. Use match filter and use another filter to compare
performances.
e. Understand the effect of pulse shaping on eye diagram
f. Understand the effect of pulse shaping on BW
g. Understand the effect of pulse shaping on CCDF
