2results about How to "Reduce storage load" patented technology

The application provides a direct current offset correction circuit based on a lookup table, a zero intermediate frequency receiver and a direct current offset correction method based on a lookup table. The direct current offset correction circuit based on a lookup table comprises a storage module, an analog coarse correction module and a digital fine correction module. In the receiving channel of the zero intermediate frequency receiver, the analog coarse correction module is used to perform analog coarse correction on the direct current offset in the analog signal, and the digital fine correction module is used to perform digital fine correction on the direct current offset in the digital signal. The analog intermediate frequency correction and the digital baseband correction are considered, and the correction precision of the direct current offset is improved. Meanwhile, the direct current offset correction lookup tables generated by radio frequency and intermediate frequency devices are separately established. During correction, indexing and operation are performed based on the analog coarse correction module and the digital fine correction module. Only a small number of calculation input correction parameters need to be saved, the total capacity of the lookup table is reduced, and the storage load of the storage module is reduced.

Embodiments of the present application disclose a data storage method, related device and equipment, which are used for avoiding resource waste of data storage. The method comprises the following steps: obtaining to-be-transmitted data, performing fragmentation processing on the to-be-transmitted data according to a target data type to obtain K pieces of fragmented data and an actual storage amount corresponding to each piece of fragmented data, allocating a preset storage amount to each piece of fragmented data according to the actual storage amount corresponding to each piece of fragmented data, determining a storage address of each piece of fragmented data if a data tag of each piece of fragmented data exists in a historical storage record, the historical storage record comprising a mapping relationship between data tags and storage addresses within a historical time, sending a resource creation request to a server according to the storage address of each piece of fragmented data, so that the server creates storage resources matching the preset storage amount for each piece of fragmented data, and sending the K pieces of fragmented data to the server, so that the server stores the K pieces of fragmented data.
