Embodiment 1

[0093] In the embodiment of the present invention, in order to determine the number of segments more flexibly and reasonably, the determination of the target number of segments for the sequence to be encoded according to the length of the sequence to be encoded and the transmission code rate includes:

[0094] A target number of segments for the sequence to be encoded is determined according to the length of the sequence to be encoded, the transmission code rate, and a preset first function.

[0095] Specifically, a preset first function is stored in the sending end. When determining the target number of segments for the sequence to be encoded according to the length of the sequence to be encoded and the transmission code rate, it may be based on the length of the sequence to be encoded. The length, the transmission code rate, and the preset first function determine the target number of segments for the sequence to be encoded.

[0096] The first function saved in the sending e...

Embodiment 2

[0120] In order to perform segmentation more accurately, so that the dividing point can successfully capture the segmentation boundary, after determining the target number, determine whether to segment according to the target number, you can judge whether the preset condition is met, if the preset condition, the sequence to be coded can be segmented according to the target number, if the condition is not satisfied, the determined target number can be adjusted, and the sequence to be coded can be segmented according to the adjusted target number. On the basis of the above embodiments, in the embodiment of the present invention, before segmenting the sequence to be encoded according to the target quantity, the method includes:

[0121] determining a temporary value according to the length of the sequence to be encoded and the target quantity;

[0122] Determine a proportional threshold corresponding to the transmission code rate according to the transmission code rate;

[0123]...

Embodiment 3

[0134] When judging the size of the temporary value and the ratio threshold, the process of determining the ratio threshold may be different for different transmission code rates. On the basis of the above-mentioned embodiments, in the embodiment of the present invention, according to the transmission code rate, Determining the ratio threshold corresponding to the transmission code rate includes:

[0135] If the transmission code rate is less than the preset first code rate threshold, determine that the ratio threshold corresponding to the transmission code rate is a preset value.

[0136]In the embodiment of the present invention, the first code rate threshold and the preset value are stored in the sending end. When determining the ratio threshold corresponding to the transmission code rate, the transmission code rate may be determined according to the size of the transmission code rate and the first code rate threshold. A ratio threshold corresponding to the code rate. If th...

Abstract

The invention discloses a coding method and device, electronic equipment and a storage medium, which are used for solving the problem of inflexible segmentation of a sequence to be coded in the priorart. The method comprises the following steps: determining a target number of sequence segments to be coded according to the length and transmission code rate of a sequence to be coded; According to the target number, carrying out segmentation processing on the to-be-coded sequence; And encoding each subsequence subjected to the segmentation processing, and cascading after encoding. In the embodiment of the invention, the target number of the sequence segments to be coded is determined according to the length and the transmission code rate of the sequence to be coded, and the sequence to be coded is segmented according to the target number. And the sequence to be coded is flexibly segmented, so that the coding performance is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an encoding method, device, electronic equipment and storage medium. Background technique [0002] As the fifth-generation mobile communication technology (5th-Generation, 5G) eMBB (Enhanced Moblie BroadBand, enhanced mobile broadband) scene control channel coding scheme polar codes (Polar Codes), is a new type that can achieve binary symmetric channel capacity Encoding method, and has excellent decoding performance. [0003] However, the polar code has a large storage capacity and latency when the mother code length is large, so 5G stipulates that the maximum length of the polar code mother code for downlink transmission is 512 bits, and the maximum length for uplink transmission is 1024 bits. However, due to the impact of Massive Multiple-Input Multiple-Output (Massive Multiple-Input Multiple-Output, Massive MIMO), the length of the information sequence of uplink...
