Abstract

The invention discloses a low-delay 5G baseband signal generation method, and specifically relates to the technical field of wireless communication. The low-latency 5G baseband signal generation method adopts a low-latency 5G baseband signal generation device including a system synchronization module, a preprocessing module, an IFFT module, an added CP module, a rate matching module, a spectrum shift module and a synchronous combination module. 5G The system parameters of the system enter the system synchronization module to provide parameters for the preprocessing module, adding CP module, rate matching module, spectrum shifting module and synchronous combining module; adopt CP direct output preprocessing technology and time domain rate matching technology, adopt time domain rate Matching technology greatly reduces baseband processing delay.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a low-delay 5G baseband signal generation method. Background technique [0002] After years of explosive growth, mobile communication network technology has experienced 2G, 3G and 4G, and each generation has a ten-year development cycle. Although mobile communication technology has undergone 30 years of development and updating, compared with the first generation mobile communication system, its data transmission rate has been greatly improved, but in the 21st century of data transmission explosion, mobile communication services are still facing great challenges . Therefore, it is the current development trend to study the key technologies related to 5G mobile communication, and 5G will replace 3G and 4G in the near future to become a new generation of mobile communication technology. On June 14, 2018, the independent networking (SA, Standalone) function of the f...
