The application relates to the communication technical field, and discloses an encoding method, a decoding method, a communication device and a communication system. Based on the method, the error correction performance and the decoding performance under a medium or short code length are improved by twice lifting of a base matrix. Since the element value of the second base matrix after the first lifting is modified, flexible matrix design is realized, the orthogonality between rows of the base matrix is improved, and the error correction performance and the decoding performance are further improved.

This invention relates to airspace coding, specifically to a multi-level unified coding system for low-altitude airspace. The system includes a coding hierarchy architecture module, which designs and constructs an eight-level coding architecture from the national level to the building level; a coding inheritance and short code setting module, which designs inheritance logic to achieve reversible traceability of codes and designs short code rules to improve coding efficiency; a coding fusion module, which combines a planar coordinate framework and altitude coding to achieve integrated coding of planar and altitude spaces; a coding splicing and storage module, which designs coding splicing rules, file naming conventions, directory hierarchy structures, and unified attribute fields to facilitate system storage, parsing, front-end loading, and spatial indexing; and a multi-standard compatibility module, which establishes compatibility conversion rules between grid data and various existing standards to ensure seamless integration with existing industry data systems. The technical solution provided by this invention overcomes the shortcomings of achieving accurate low-altitude airspace division, efficient traceability, and cross-industry data interoperability.

The present application provides a video compression method and device for dynamically adjusting the position of elements of a recent motion vector array in inter-frame prediction coding. The method and device effectively reduce the number of bits consumed in coding motion vectors and greatly improve coding efficiency by dynamically adjusting the elements of the motion vector array with high occurrence frequency to a specific part of the motion vector array and using a short code word to represent the storage address of the specific part.

This application discloses a method, apparatus, device, and storage medium for generating short links, belonging to the field of computer technology. The method includes: receiving a service request from a user terminal, the service request carrying long link information, the service request requesting the generation of N short links, where N is an integer greater than 1; generating N short codes based on a continuous factor, a random factor, and the long link information, each short code being a string, the continuous factor including a first string sequence comprising N regular first strings, and the random factor including N random second strings; performing deduplication processing on the N short codes, and generating N target short links based on the deduplication result, thereby reducing the probability of hash collisions in scenarios with a large number of short link requests and improving the effectiveness of the short links.

The application provides a material attribution type short chain generation method based on a pseudo-random hash algorithm, and relates to the technical field of electric digital data processing. The method comprises the following steps: normalizing and splitting a link service data to generate a plurality of material attribution units and construct offline material attribution basic records; encoding and mapping the offline material attribution basic records to generate a service short code and encapsulate the service short code with a material receiving mark to generate a UrlLink access entrance; performing material paving confirmation and attribution state determination on a material to be paved to obtain a material attribution state determination result and perform state solidification processing on the plurality of material attribution units to generate an activated material attribution short chain; and performing matching verification on a UrlLink receiving field to obtain a matching verification result and generate a branch jump decision instruction to perform a jump operation, so as to realize accurate attribution association of offline material delivery and online access entrance, and improve the attribution recognition ability and data tracing ability of the material attribution short chain.
