A MATLAB-based project designed to simulate digital signal transmission in the presence of impairments.
The goal is to understand and characterize the effects of these impairments on signal integrity.
The final product is a generic application that allows users
to modify various transmission parameters and observe their impact at the receiver
through selected diagrams and figures of merit (FOMs)
High speed digital systems require data transfer rates equal to or higher than 10GHz.
These rates, and the resulting system bandwidths,pose severe design challenges in minimizing
the system-induced distortions that affect negatively the binary signal integrity and the ability
of the decoding system to recover the digital data correctly.
These distortions can originate from both stochastic processes, such as AWGN and phase jitter,
or from deterministic, such as signal-shaping effects and Xtalk.
The aim of this project is to explore the various system-induced distortion mechanisms
and analyze their effects on signals integrity.
I will show how the signals’ characteristics are affected by those distortion mechanisms,
and estimate the signals’ distortion-induced FOMs (Figure of Merit’s), such as ,
SNR (Signal to Noise Ratio), EVM (Error Vector Magnitude), etc. as well as provide various graphs
aimed to illustrate those effects such as eye-diagrams, histograms.
