pulse-shaping

MATLAB-based wireless communications simulator for transmitting data over a high-mobility doubly-selective fading channel for various modulation techniques (OFDM, OTFS, ODDM)

Active Development, Project Log

This repository contains some useful scientific functions that I created for my daily research work.

Communication Lab (2019 Spring)

Python implementation of a digital communication system with PCM, μ-Law, line coding, AWGN channel and BER analysis.

A full simulation of a QPSK communication system with CFO in MATLAB.

A differentiable model of a superconducting control line — DAC, filter, IQ mixer, amplifier — wired to a three-level transmon in JAX, with hand-derived adjoints and a gradient checked against finite differences. Finds a bandwidth threshold below which classical pre-distortion makes the gate worse. Tesseract Hackathon 2026, Track 03.

Pulse-level simulation of complex-frequency (CF) control pulses with Qiskit Dynamics: custom parametric pulse class, calibration library, and Rabi experiments on a 2-qubit transmon model.

Energy–fidelity limits and optimal voltage pulses for preparing a prescribed electron and its Fermi sea through interacting quantum Hall edge channels using one upstream control. Includes analytic derivations, a guided tutorial, and reproducible numerical checks.

Power Spectral Density analysis, line coding schemes (Polar/AMI/OOK), PAM pulse shaping, and eye diagram generation in MATLAB
