System and method for index modulation based joint mode frequency hopping with vortex electromagnetic waves for anti-jamming

A system of index modulation based joint mode frequency hopping with vortex electromagnetic waves for anti-jamming, wherein the system comprises a transmitter and a receiver;

• the transmitter and the receiver each comprises a subcarrier index selector configured to determine a carrier for signal transmission;
• the transmitter transmits an input signal to a transmit antenna module via a signal modulation module;
• after the signal from the transmit antenna module is received by a receive antenna module, a binary demodulation signal is output after the signal is processed by a carrier demodulation and a band pass filter (BPF) sequentially;
• wherein, the transmitter is provided with a selector for selecting diversely signal transmit carriers between the input signal and the transmit antenna module, the signal transmit carrier selector is formed by a one-way serial connection of a transmit combination mapper and two parallel transmit index selectors, and the two parallel transmit index selectors are respectively a transmit orbital angular momentum (OAM) mode index selector and a transmit subcarrier index selector;
• the transmit antenna module is an OAM transmit antenna module;
• the receiver is provided with a signal receive carrier selector that is strictly synchronized with the signal transmit carrier selector between the receive antenna module and the BPF, the signal receiving carrier selector is formed by a direct one-way serial connection between two parallel receive index selectors and a receive combination mapper, the two parallel receive index selectors are respectively a receive OAM mode index selector and a receive subcarrier index selector;
• a received signal of the receiver is sequentially transmitted to the receive combination mapper, the two parallel index selectors, and the BPF;
• the receive antenna module is an OAM receive antenna module;
• a group of fast Fourier transformation (FFT) modules are provided between the BPF and an output signal;
• after the signal transmitted from the OAM transmit antenna module is received by the OAM receive antenna module, the signal is processed by the receive combination mapper, the two parallel receive index selectors, the BPF, and the FFT module sequentially, and the binary demodulation signal with jamming eliminated is output as binary information bits.
