Abstract

One or more embodiments of this specification provide an anti-interference communication method and electronic device, which can solve the problem of communication quality degradation caused by inter-symbol interference and narrowband interference. The electronic device includes a memory, a processor, and a computer program stored on the memory and executable on the processor for performing the anti-jamming communication method. The anti-interference communication method includes: the signal transmitting end allocates the information symbols of the initial modulation information to the time-delay-Doppler domain resource grid to obtain mixed-hop symbol signals, and performs inverse symplectic Fourier transform on the mixed-hop symbol signals Transform with Heisenberg to obtain the time-domain transmission signal; transmit the time-domain transmission signal to the communication channel, and the signal receiving end receives the corresponding time-domain reception signal; perform Wigner transform and symplectic transformation on the time-domain reception signal Fourier transform is performed to obtain a received signal; information symbol sequence detection is performed on the received signal to determine the communication information sent by the signal transmitter.

Description

technical field [0001] One or more embodiments of this specification relate to the field of communication technologies, and in particular, to an anti-jamming communication method and electronic equipment. Background technique [0002] In wireless communication, in order to resist the influence of complex wireless communication environment on communication quality, and to improve communication transmission rate and frequency band utilization, waveform design technology is often used. Good waveform design helps to improve communication quality and communication speed. For example, the Orthogonal Frequency Division Multiple Access (OFDMA) access technology used in 4G can well combat the frequency selectivity in the wireless transmission environment fading, can obtain high spectrum utilization. [0003] The existing OFDMA technology is based on Orthogonal Frequency Division Multiplexing (OFDM) modulation, which is extremely sensitive to the Doppler effect. The carriers are no ...
