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.
