Abstract

The invention discloses a communication method and system capable of resisting continuous wave interference. The method comprises the following steps: step S110, a sending end generating a training sequence with start signaling information as a signaling sequence, and marking it as C1; performing time frequency transformation on the signaling sequence C1, obtaining a control frame head, and marking it as C2; and at the same time, generating a sub signal frame to be transmitted; step S120, the sending end multiplexing the control frame head C2 and the sub signal frame to form a signal frame group; and step S130, the sending end sending the signal frame group after the signal frame group is processed. According to the communication method and system capable of resisting the continuous wave interference, under the condition that there is no additional system cost, the signal processing of a receiving end is simple and efficient, high robustness is maintained under quite high continuous wave interference, and the communication performance of the communication system in an extreme transmission environment is further improved.

Description

technical field [0001] The invention relates to the technical field of signal communication, in particular to a communication method and system for resisting continuous wave interference. Background technique [0002] The rapid development of modern communication technology makes people's demand for wireless communication services show explosive growth and diversified development. The diversification here may be the diversification of the use environment of the wireless communication, the diversification of the wireless communication service type or the service quality (QoS, Quality of Service), and the like. For example, in a digital TV broadcasting system, for different usage environments and different TV signal clarity levels, the sending and receiving sides can adopt different coding efficiencies, Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) lengths, and guard interval lengths. , Diversity multiplexing and other measures ...
