Simulation Of Frequency Hopping Spread Spectrum And Jamming In Wireless Communication Systems

Abstract

In this paper, a simulator is designed to simulate a frequency hopping spread spectrum (FHSS) communication system using VisSim/Comm software which is mainly implemented to design and analyze problems of communication systems. The simulation of FHSS system requires to simulate both the transmitter and the receiver as well as the medium (noise/jamming) between them. This paper presents how these three items are simulated and more over how the performance of such system can be evaluated. Among many methods of evaluation, the Bit-Error-Rate (BER) plot is adopted in this paper which is defined as the probability of bit error (Pe) against the ratio of bit energy (Eb) to the noise energy No (Eb/No).
