Problems solved by technology

[0004] Solving the problem of channel dynamics is a challenging task
Therefore, adjusting CTC based on indirect indicators cannot achieve optimal results
Second, some statistical features are very susceptible to channel dynamic interference, resulting in the performance of feature-based decoding models often failing

Abstract

Embodiments of the invention provide a channel adaptive cross-protocol communication system and method. The system comprises a CTC decoding module and an online learning module, wherein the CTC decoding module is configured to extract features of each CTC symbol in a CTC packet according to a Text-CNN decoding model to obtain decoded data; and the online learning module is configured to update theText-CNN decoding model online according to the decoded data, so that the Text-CNN decoding model adapts to the dynamic channel environment. A channel adaptive cross-protocol communication system andmethod provided by the embodiments of the invention propose a general, lightweight online adaptive CTC framework, comprising a Text-CNN based decoding model to "track" channel changes and an online learning module to adjust the Text-CNN decoding model to maintain a reliable and stable communication performance, thereby being able to adapt to environmental noise interference and effectively reducing the bit error rate.

Description

technical field [0001] The invention relates to the communication field, in particular to a channel adaptive cross-protocol communication system and method. Background technique [0002] With the continuous development of the Internet of Things, various wireless devices have been deployed on a large scale, but at the same time, problems such as high deployment density of wireless devices, difficulty in coordination between different wireless protocols, and low utilization of channel resources have also been encountered. These problems gave birth to Cross-Technology Communication (CTC), which aims to realize the direct interconnection and intercommunication of heterogeneous wireless devices (such as WiFi, Bluetooth, ZigBee). Existing CTC technologies often use a "side channel" (side channel) that can be accessed by both parties to transmit data, such as the energy of data packets, time intervals, and status changes of overlapping channels. [0003] Most current cross-protoco...
