Problems solved by technology

[0003] This method has the following disadvantages: it needs to generate useless sequences in the middle, which wastes computing resources and increases delays; it needs to add processing modules to extract useful sequences from all sequences; the generated useful sequences are discontinuous in clock cycles and may need to be cached The device stores all the sequences and converts them into continuous output to facilitate the processing of subsequent modules

Abstract

The embodiment of the invention discloses a pseudo-random sequence generation method, a pseudo-random sequence generation device and a computer readable storage medium, which are used for skipping useless sequences corresponding to RGB in a BWP and shortening operation delay. Useful pseudo-random sequence values can be output in continuous clock periods, a large-scale buffer does not need to storeall sequences, computing resources are saved, and delay is shortened. The method provided by the embodiment of the invention comprises the following steps: acquiring sequence states of a first m sequence and a second m sequence; obtaining the useful RGB distribution information of the first m sequence and the second m sequence; and calculating a pseudo-random sequence vector according to the distribution information of the useful RGB and the sequence state.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for generating a pseudo-random sequence, a generating device and a computer-readable storage medium. Background technique [0002] In the prior art, when calculating useful pseudo-random sequences, although the beginning of a useless sequence can be skipped through a mask, some useless sequences in the middle cannot be skipped when the internal phase of the sequence is discontinuous. In the prior art, all sequences are usually generated in a continuous manner and then corresponding useful sequence values ​​are extracted therefrom. [0003] This method has the following disadvantages: it needs to generate useless sequences in the middle, which wastes computing resources and increases delay; it needs to add processing modules to extract useful sequences from all sequences; the generated useful sequences are discontinuous in clock cycles and may need to be cached The devi...
