Two-Dimensional New Communication Technology for Networked Ammunition

In order to improve the transmission data rate and the three-resistance characteristics of the network ammunition communication link, this paper proposes a new communication technology with two dimensions. In this technology, orthogonal frequency division multiplexing (OFDM) is used for one-dimensional data transmission, and the G-function-driven subcarrier frequency change rule in differential frequency hopping (DFH) is used for two-dimensional data transmission, which breaks through the conventional idea of using carrier amplitude frequency phase modulation information, and establishes a new two-dimensional communication model based on DFH-OFDM. The theoretical analysis and simulation results show that the proposed two-dimensional new communication technology, without changing the original communication system and signal characteristics, effectively reduces the probability of signal interception, improves the communication system capacity, and has good three-resistance performance.
