Abstract

One or more embodiments of the present specification provide an anti-interference communication method and electronic equipment, which can solve the problem of reduced communication quality caused byinter-symbol interference and narrowband interference. The electronic equipment includes a memory, a processor, and a computer program stored on the memory and operable on the processor for performingan anti-interference communication method. The anti-interference communication method comprises the following steps that: a signal sending end allocates an information symbol of initial modulation information to a delay-Doppler domain resource grid to obtain a mixed jump symbol signal, carries out inverse symplectic Fourier transform and Hesenberg transform on the mixed jump symbol signal to obtain a time-domain sending signal, transmits the time-domain sending signal to a communication channel; and a signal receiving end receives the corresponding time-domain receiving signal, carries out Wigner transform and symplectic Fourier transform on the time-domain receiving signal to obtain a receiving signal, performs information symbol sequence detection on the receiving signal, and determinescommunication information sent by the signal sending end.

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 ...
