A gateway and information demodulation method

Abstract

The invention discloses a gateway and an information demodulation method. The gateway includes a configuration module, a signal receiving module, a signal conversion module and at least two sets of demodulation modules. The configuration module and each of the at least two sets of demodulation modules The group demodulation module connection is used to initialize each group of demodulation modules, and the initialization includes configuring the demodulation rules corresponding to each group of demodulation modules in at least two groups of demodulation modules; the corresponding demodulation rules of each group of demodulation modules The tuning rules are different; the signal receiving module is connected with the signal conversion module to receive the initial LoRa radio frequency signal of the preset frequency band, and the initial LoRa radio frequency signal is processed for the first time to obtain the target LoRa radio frequency signal, and the signal is sent to the signal conversion module. The target LoRa radio frequency signal; the signal conversion module is connected with each group of demodulation modules in at least two groups of demodulation modules to receive the target LoRa radio frequency signal, and the target LoRa radio frequency signal is processed for the second time to obtain a digital IQ signal. Each group of demodulation modules sends digital IQ signals.

Description

technical field [0001] The present invention relates to long-distance radio (LoRa, Long Range Radio) technology in the communication field, and in particular to a gateway and an information demodulation method. Background technique [0002] In the long-distance radio wide area network (LoRaWAN, Long Range Radio Wide Area Network), the simultaneous receiving and processing capability of the gateway (base station) is limited to only 8 data packets, so that more than 8 data packets arrive at the same time When using a gateway (base station), data packets sent by communication terminals that are far away from the gateway (base station) or in a complex wireless environment are always easily discarded, which not only affects the timeliness of data collection by the gateway (base station), but also greatly wastes communication Terminal resource overhead. At present, stacking multiple radio frequency gateway modules in the gateway (base station) is usually used to solve the above p...

[0002] In the long-distance radio wide area network (LoRaWAN, Long Range Radio Wide Area Network), the simultaneous receiving and processing capability of the gateway (base station) is limited to only 8 data packets, so that more than 8 data packets arrive at the same time When using a gateway (base station), data packets sent by communication terminals that are far away from the gateway (base station) or in a complex wireless environment are always easily discarded, which not only affects the timeliness of data collection by the gateway (base station), but also greatly wastes communication Terminal resource overhead

At present, stacking multiple RF gateway modules in the gateway (base station) is usually used to solve the above problems, but the effect is not particularly good
