10. Time-Frequency Representation of Signal of Interest (GMSK): Piecewise Polynomial Representation
Gradient Operation at Level 1
Gradient Operation at Level 2 – The Piecewise Polynomial is Decomposed as a Impulse Functions
Question: Assuming that this sequence of impulses can be transmitted and received with high fidelity, is this characterization
good enough to model GMSK based communication system?
