Abstract: A positioning method and a communication device are provided, which relate to the field of communication technologies. The method includes: determining first information. The first information includes at least one of the following: direction information of a target beam, energy change information of the target beam, LOS path indication information, and beam identification information. The first information is used to determine positioning information of the first device. The LOS path indication information is used to indicate whether the target beam is an LOS path. The beam identification information is identification information of the target beam.

Abstract: The present invention discovers a recipe generation system for a cooking appliance and the cooking appliance. The recipe generation system comprises an operation unit; a weight detection unit configured to measure initial weights of various cooking materials sequentially added into the cooking appliance and measure the overall weight of the cooking materials during cooking and finishing cooking; a timing unit; a parameter calculation unit configured to obtain proportions of the cooking materials based on the initial weights of the cooking materials and calculate weight losses of different cooking materials at different time points; and a parameter determination unit. The present invention can determine dish compositions, key cooking elements for forming the dish and cooking procedures by detection and information processing of a series of operations during cooking for use in subsequent cooking procedures.

Abstract: The present invention provides a ground-based augmentation system capable of predicting a tropospheric refractive index with high precision. The system includes a ground base station and an airborne receiver. The ground base station includes a ground acquisition device, a processor, and a transmitter. The ground acquisition device is configured to acquire meteorological parameters of a plurality of years, and use the acquired meteorological parameters as historical data. The processor is configured to call the historical data and establish a back propagation (BP) neural network to predict a refractive index. The transmitter is configured to send the refractive index predicted by the processor to the airborne receiver. With the present invention, the tropospheric refractive index is predicted for different weather conditions, thus improving the precision of tropospheric refractive index prediction.
