Embodiment Construction

[0016] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.

[0017] figure 1 A flow chart of an encoding method based on linear block codes provided by an embodiment of the present invention. Such as figure 1 As shown, this embodiment specifically includes the following steps:

[0018] Step 101. Encode an input information sequence according to a (40, 14) linear block code coding matrix to obtain a code stream sequence;

[0019] Step 102, output the code stream sequence.

[0020] This embodiment encodes according to the linear block code encoding matrix of (40, 14), and can realize the linear encoding of (40, A), that is, this embodiment can encode an input information sequence whose length is greater than or equal to 1 and less than or equal to 14.

[0021] Specifically, the linear block code encoding matrix of (40, 14) above may be any one of the matrices shown in Ta...

Abstract

The invention relates to a coding method and device based on a linear block code. The method comprises the following steps: coding an input information sequence according to a linear block code coding matrix (40, 14); and outputting a code stream sequence. According to the invention, coding of which the information bit length is less than or equal to 14 can be realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a coding method and device based on linear block codes. Background technique [0002] In modern communication systems, linear block codes are usually used to encode short-length control information, for example: Transport Format Combination Index (Transport Format Combination Index) in Wide Code Division Multiple Access (WCDMA) system Format Combination Index (TFCI for short) coding, Physical Uplink Control Channel (Physical Uplink Control CHannel, PUCCH for short) and Physical Uplink Shared Channel (Physical Uplink Shared CHannel, referred to as: PUSCH) encoding. Among them, the PUCCH encoding in the LTE system adopts the (20, 13) linear block code encoding matrix to realize the (20, A) linear encoding, where 1≤A≤13; the PUSCH encoding adopts the (32, 11) linear block code encoding matrix to realize the linear encoding of (32, O), where 1≤O≤...
