Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, existing error correction codes are inadequate for efficiently transmitting very short-length data, particularly in scenarios requiring optimal Hamming distance for reliable error correction, such as control information signals.
Innovation Solution
The use of a block code composed of Walsh and mask basis sequences, specifically an improved Reed-Muller code, is employed for encoding and decoding short-length information bits, optimizing the minimum Hamming distance and reducing decoding complexity.

Engineering Contradiction Analysis
1Reliability
If existing error correction codes are used for short-length data transmission, then the transmission can be performed, but the error correcting performance is inadequate and the minimum Hamming distance is not optimized
Solution Approach 1:
The patent changes the fundamental parameters of the code structure by using block codes with optimized minimum Hamming distance specifically designed for short-length data. The code length and dimension parameters are carefully selected to maximize error correction capability for small data sizes, transforming the inadequate error correction performance into optimized reliability.
2Reliability
If a block code with optimized minimum Hamming distance is used, then the error correcting performance is improved, but the decoding complexity increases
Solution Approach 1:
The decoding process is segmented into two independent stages: first decoding the outer block code to correct errors, then decoding the inner convolutional code. This segmentation allows each decoder to be optimized independently, reducing the overall decoding complexity while maintaining the benefits of the optimized minimum Hamming distance from the block code portion.
3Ease of manufacture
If conventional coding schemes are used for short-length data, then the implementation is straightforward, but the transmission reliability is insufficient
Solution Approach 1:
The patent employs a composite coding structure combining block codes with optimized minimum Hamming distance and convolutional codes. This composite approach leverages the error correction strengths of block codes for short-length data while maintaining implementation feasibility through the well-established convolutional coding component, achieving both reliability and practical implementability.
