Security features of NC-OFDM transmission

This project was part of our study of NC-OFDM transmission at WINLAB. The study was mainly conducted by Gokul Sridharan (a post-doc researcher at the time). The goal of this work was to highlight the physical layer security features of a NC-OFDM transmission. The study looked from an eavesdropper’s perspective and tried to obtain the necessary parameters using Cyclic-autocorrelation function (CAF) for further decoding of the NC-OFDM signal.
