ASK, QAM, PSK, FSK, MSK simulations and analysis.
Lab exercises for Digital Communications I course, 6th Semester 2021 of the Electrical and Computer Engineering School at the National Technical University of Athens.
In this course I used MATLAB to simulate transmitter-channel-receiver systems using various modulation techniques, and compare their spectrum and bit error rate.
I created my own version of the pwelch function.
I created orthogonal, Hamming, Kaiser and Parks-McClellan filters and compared them.
ASK modulation.
ASK modulation using Nyquist filters. Comparison of different roll-off factors and filter order.
PSK and QAM modulation.
Coherent and non coherent FSK modulation. MSK modulation and comparison of various systems.
