Abstract

The invention discloses a physical layer cross-technology communication method and device, which are used for realizing direct communication from ZigBee to BLE, and the method comprises the following steps: receiving a ZigBee signal; dividing the ZigBee signal into a plurality of signal segments, wherein the signal segments comprise anti-offset segments; identifying the rule of the anti-offset segment, and determining a decoding algorithm according to the rule of the anti-offset segment; according to the decoding algorithm, performing decoding on the ZigBee signal; and identifying the decoded ZigBee signal. According to the method, a ZigBee signal is divided into a plurality of signal segments, the signal segments comprise anti-offset segments, and the rule of the anti-offset segments is identified to obtain a decoding algorithm; and by using the decoding algorithm, the ZigBee symbol can be decoded with very low processing complexity, and very high decoding precision can be realized at the same time. The method can be widely applied to the technical field of Internet of Things communication.

Description

technical field [0001] The invention relates to the technical field of Internet of Things communication, in particular to a physical layer cross-technical communication method and device. Background technique [0002] At present, cross-technology communication (CTC) methods to realize direct communication between heterogeneous devices are mainly divided into two categories, one is packet-level CTC, which uses packet-level information to realize cross-technology message communication. The other type is physical layer CTC, which uses physical layer information to achieve cross-technology message communication; the physical layer CTC at the receiver side transfers the processing complexity to the receiver. LEGO-Fi and XBee are two typical representatives of CTC on the receiver side, they respectively realize the direct communication from ZigBee to WiFi and ZigBee to BLE; in addition to the process of reusing the standard modules of their respective receivers, both solutions are...
