Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently encoding and decoding data using polar codes, particularly in determining the number of segmentations and deciding when to perform segmentation, which affects decoding performance in 5G communication systems.
Innovation Solution
A method and apparatus for determining the number of segmentations in a wireless communication system by generating a bit sequence and performing code block segmentation based on the number of bits, allowing for stable and efficient encoding and decoding using polar codes, including the use of a controller to manage segmentation and encoding/decoding processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If code block segmentation is performed for polar code encoding, then decoding performance is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the bit sequence into multiple code blocks based on the total number of bits. When the bit sequence length exceeds a threshold, it is segmented into multiple blocks that are independently encoded and decoded, improving decoding performance while managing complexity through controlled division
2Reliability
If the number of segmentations is increased, then decoding performance is improved, but processing time increases
Solution Approach 1:
The patent dynamically adjusts the segmentation parameter (number of code blocks) based on the total number of bits in the bit sequence. By establishing a relationship between bit sequence length and optimal segmentation number, the system achieves improved decoding performance while minimizing processing time through parameter optimization
