An Innovative High-Frequency Wireless Communication Technique Inspired by Multi-Frequency Carrier Signals

Modern intelligent broadcasting technologies using Internet-of-Things (IoT) and Wireless Communication mediums are playing an important role to connect multiple heterogeneous devices. This fulfills the requirement to achieve advanced and robust communication systems. This paper describes a data transmission technique using a high-frequency generator reflex klystron. Here, the high-frequency multi-level shift keying techniques are generated with the help of a single reflex klystron, namely M-ary High-Frequency Shift Keying (MHFSK). The reflex klystron plays the primary role to generate multiple independent high-frequency signals. In this scheme, the high-frequency carrier signal is selected through a sequence of binary bits which control the reflector voltage. As a result, this modulation system creates multiple high frequencies which act as an important parameter of this proposed multi-frequency modulation scheme. Here, the main goal is to improve the overall efficiency compared to other binary digital modulation systems. This new concept has been verified through an experimental framework.
