Secrecy Capacity Improvement of Wireless Channel

Abstract

In the modern case scenario of intended communication the secrecy related issue becomes very much of concern. A passive eavesdropper can cause leakage of information. System optimization demands that eavesdropper should not extract considerable amount of information. Our analysis exhibits that adding artificial noise alongside jammer can degrade eavesdropper capacity. We build up our analysis based on a circumstance where transmitter has multiple antenna and jammer is also placed and both of them are communicating with the receiver and eavesdropper in a synchronizing and planned sequence and information which will eventually serve our purpose.
