Research and Development of an Experimental Device for Military Communication Using Multi-level Amplitude Shift Keying

Abstract

Ensuring "timely, accurate, confidential, and secure" communication is a core requirement for military communication systems. Traditional communication systems often use amplitude modulation (AM) due to its simple design and ease of implementation. However, the major drawback of AM is its high sensitivity to noise, making it suitable only for long-wave transmissions, such as AM radio, and challenging to integrate modern technologies like 4G and 5G into military communication systems. This paper presents the research and development of an experimental military communication device using multi-level shift keying (MASK) modulation. The study explores the mathematical foundation, design, and construction of the MASK modulation and demodulation system. The experimental device was tested under varying noise levels and transmission conditions to evaluate its performance. Results indicate that the MASK-based system significantly improves noise resistance compared to AM systems, ensuring reliable communication even in high-interference environments. These findings demonstrate the potential of MASK for integration into next-generation military communication systems, addressing the stringent demands of modern combat and adverse conditions.
