Performance Analysis of MIMO-OFDM For LTE Tactical Communication Systems in Jamming Environment
Key challenges for armed forces are the enabling of a highly mobility; full command and control capabilities; critical-infrastructure protection; and leveraging of the commercial, off-the-shelf telecommunications products in military networks. Commercial off-the-shelf (COTS) based solutions serve speed time to market, are easier to maintain, and offer affordable solution when compared to proprietary, government-unique systems. COTS-based LTE are communications technologies, mature, proven reliable and robust, easily deployable, and scalable. However, reliable communications in the COTS-based LTE system are critical in defense applications and the ability to protect jamming signal is key to the tactical communication systems. The objective of this paper is to analyze the performance of the MIMO-OFDM for LTE tactical communication systems in jamming environment. In this research, the average Bit Error Rate (BER) for the 2x1 SFBC 16-QAM and 64-QAM modulation schemes in the asynchronous off-tones (AOTJ) jamming environment with different dynamic ranges of the colored noise jamming is analyzed. MATLAB Monte-Carlo simulations are used to evaluate the performance of this research.
