Unequal/Adaptive Error Protection TRIZ Cases
- vRAP HARQ Prediction for Cloud RAN Decoding Fluctuations
Extrinsic-information HARQ prediction helps virtualized RAN decoding adapt to cloud compute fluctuations while avoiding unnecessary retransmissions.
- Priority-Based Polar Coding for Reliable 5G Control Information
Priority-grouped polar coding adds stronger protection to critical 5G control bits, improving grant, CQI, and ACK/NACK reliability without full coding overhead.
- Adaptive Concatenated ECC for Varying Flash Cell Error Rates
Different ECC protection levels are assigned within one flash code word to match cell error variation and improve reliability without extra power.
- MRI Data Link Encoding by Signal Importance
Critical MR signals get stronger encoding while less sensitive data gets lighter protection, improving MRI link robustness and efficiency.
- Polar Code Construction Using Dynamic Sorting Indices
Dynamic sorting indices replace stored vectors in polar code construction, cutting memory use while maintaining reliable wireless transmission.
- Polar-Coded Control Channels With Joint CRC for Multi-User Decoding
Multiplexed control data for multiple users is jointly polar-coded with group CRC to cut overhead and improve decoding reliability.
- Context-Based Decoder Feedback for Error-Prone Data Streams
Higher-layer context guides decoder feedback to correct transmission errors, improve accuracy, and cut processing overhead.
- Wireless Audio Packet FEC for Low-Latency Error Recovery
Parity blocks matched to wireless packet timing let receivers rebuild lost audio data without retransmission, reducing delay and AV desync.
- Polar Code Construction for Multi-Rate Blocks With Reduced Memory
On-the-fly sorting indices replace large stored vectors in polar coding, reducing memory while supporting multiple block sizes and rates.
- XR Data Coding by QoS Layer for Low-Latency Wireless Transmission
By coding XR data by QoS and layer priority, wireless links cut retransmission delay and reduce frame freezing in real-time delivery.
- Redundant Network Node Authentication Using Spanning Tree Ports
Mutual port authentication lets redundant automation networks use IEEE 802.1X with spanning tree reconfiguration while blocking unauthorized nodes.
- Adaptive ECC Engine for Memory Power-Reliability Tradeoffs
Dynamic ECC selection changes codeword size, rate, and algorithm by memory conditions to balance error protection, power use, and complexity.
- Joint Polar Coding of Multi-User Control Channels
Multiple users' control information is merged with individual and group CRCs into one polar code block to improve error correction in noisy channels.
- Dynamic Erasure Code Strategy for Edge Storage Encoding
Dynamic erasure code selection uses configuration and entity health data to protect edge storage with lower overhead and better availability.
