Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional convolutional coding is used without sectional redundancy checks, then the decoding process is simpler, but error detection capability and insights into error symptoms are insufficient
Solution Approach 1:
The payload is divided into multiple sections, and separate redundancy check bits are generated for each section. This segmentation allows the decoder to identify which specific section contains errors, providing granular error symptom insights without requiring complete redecoding of the entire payload, thus improving error detection capability while managing decoding complexity.
Solution Approach 2:
Sectional redundancy check bits act as intermediaries between the encoded payload and the decoder. These check bits provide additional information about error conditions in each section, enabling the decoder to make more informed decisions without significantly increasing the complexity of the core decoding algorithm.
2Measurement precision
If sectional redundancy checks are implemented, then error symptom insights and decoding performance are improved, but the overall structure and processing complexity increase
Solution Approach 1:
The payload is divided into multiple sections, and separate redundancy check bits are generated for each section. This segmentation allows the decoder to identify which specific section contains errors, providing granular error symptom insights without requiring complete redecoding of the entire payload, thus improving error detection capability while managing decoding complexity.
3Productivity
If data rates are increased, then transmission capacity is improved, but decoding performance becomes a limiting factor
Solution Approach 1:
The payload is divided into multiple sections, and separate redundancy check bits are generated for each section. This segmentation allows the decoder to identify which specific section contains errors, providing granular error symptom insights without requiring complete redecoding of the entire payload, thus improving error detection capability while managing decoding complexity.
Solution Approach 2:
Redundancy check bits are calculated in advance for each section of the payload before encoding. This preliminary action provides the decoder with pre-computed error detection information, enabling faster and more efficient error identification during high-rate transmission without compromising decoding performance.
