Enhanced MIMO Based Anti-Jamming Technique in Wireless Networks

M. Madhanraj | K. Sowmya

Abstract: MIMO-OFDM (Multiple Input Multiple Output - Orthogonal Frequency Division Multiplexing) system has been recognized as one of the most popular and competitive technique in a wireless environment nowadays. The multicarrier modulations is a techniques and It gives Advantages Like, inter carrier interference cancellation and improve packet delivery rate performance in multipath fading. Our simulation output Expose, the Better Bit Error Rate performances using LML (Linear maximum likelihood) equalizer. And also, analyzed in different fading channels for various modulation techniques in the Equalizers. The LML (Linear maximum likelihood) equalizer plays important role in Orthogonal Frequency Division Multiplexing technology. Reactive Jammer is the Most efficient jamming attacks and no other Powerful anti-jamming solutions to secure OFDM (Orthogonal Frequency Division Multiplexing) wireless communications under reactive jamming attack. In this paper, Improve anti-jamming techniques use of MIMO (Multiple Input Multiple Output) technology for jamming resilient OFDM (Orthogonal Frequency Division Multiplexing) communication. MIMO (Multiple Input Multiple Output) based anti-jamming Method that Enhanced interference cancellation and transmit pre-coding capabilities of MIMO (Multiple Input Multiple Output) technology to turn a jammed non-connectivity scenario into an operational network.
