Abstract

The invention discloses a method for adjusting an arbitrary rate resampling sequence of a parallel structure. The resampling sequence adjustment of a common case structure type is divided into 2M*M cases for discussion, and the excessively long program is not conducive to engineering implementation. The method provided by the invention utilizes the ROM core to perform resampling sequence adjustment, and only needs one-ROM-core storage instead of the case structure, which greatly reduces resource consumption. At the same time, the method uses the shift register combined with the output data ofthe ROM core to perform data selection of the resampling sequence, can correctly select the resampled data and output the data in parallel, thereby reducing the complexity of the system and improvingthe general performance of the system.

Description

technical field [0001] The invention belongs to the technical field of digital transmission, and more specifically relates to a method for adjusting a resampling sequence with an arbitrary magnification in a parallel structure. Background technique [0002] The demand for information in modern society has increased sharply. Digital transmission has replaced analog transmission due to its many characteristics such as good confidentiality, low power consumption, large capacity, and easy processing. It is widely used in various fields such as communication, radio, television, radar, and surveying. in the digital system. For high-speed digital transmission, limited by the technology level of digital logic devices, it is often impossible to use the serial processing mode to meet the high-speed and high-throughput transmission requirements, but must use a parallel architecture to realize its processing and transmission. [0003] Digital resampling technology is the key technology...
