Frequency Hopped Spread Spectrum Tutorial

Abstract

This article is about FHSS (Frequency Hopped Spread Spectrum) and one method suggested for Security improvement in it. In this report you can find an in depth information on FHSS from the basic level to the aim of the project. A detailed explanation is given about the Modulation, Frequency Hopping, PN-sequence generation, Frequency table w.r.t PN sequence which form crucial components in generation of the FH-spread signal. And finally demodulation is done and the obtained waveforms are analyzed. The whole process is simulated in the well-known simulator MATLAB. Working code is attached with this report. One method is suggested to improve the security in the FHSS.
