Error Correction/Detection Using Interleaving Techniques TRIZ Cases
- Subcarrier Sorting Circuit for Low-Delay Error Correction
Frequency-domain subcarrier sorting spreads codewords across an array to improve error correction while reducing interleaving depth and delay.
- Polar Bit Mapping for Reliable Broadcast Channel Coding
CRC bits are mapped to high-reliability polar positions while predictable timing bits use lower-reliability slots to improve broadcast signaling.
- Interleaved DFT Block Multiplexing Without Pilot Overhead
DFT interleaving and time shifting separate multi-user block transmissions without pilots, improving spectral efficiency in high-mobility links.
- Polar Code Bit Mapping for Reliable Broadcast Signaling
Reliability-aware polar coding places predictable bits and CRC bits in different code positions to improve broadcast signaling quality.
- Interleaved Multi-User Block Transmission With Non-Coherent Signal Separation
Non-coherent interleaved multiplexing separates user block transmissions while cutting pilot overhead, PAPR, and interference in high-mobility links.
- Polar Code Bit Mapping for Reliable Broadcast Signaling
Differentiated mapping places predictable bits and CRC bits in suitable polar-code positions to improve broadcast signaling reliability.
- PBCH Polar Decoding With Reliability-Based Bit Mapping
CRC and timing bits are mapped to higher-reliability polar code positions to improve PBCH broadcast transmission without major decoding overhead.
- Non-Uniform Constellation Mapping for Higher-Capacity Transmission
Non-uniform constellation mapping raises transmission capacity and improves BER/FER by narrowing the Shannon-limit gap without heavy real-time computation.
- Polar-Code HARQ Retransmission Using Interleaved Re-Encoding
Interleaved polar-code retransmission improves HARQ decoding reliability in short-packet, high-error communication channels.
- OFDM I/Q Interleaving Segmentation for Lower-Latency Transmission
Segmenting OFDM modulation symbols and interleaving I/Q components separately cuts interleaver memory and transmission delay while preserving data integrity.
- Non-Uniform QAM Mapping for Better BER in Transmitters
Non-uniform constellation mapping improves BER and FER while narrowing the Shannon-limit gap without fully sacrificing practical demapping.
- Polar Bit Placement for Broadcast Signaling Reliability
By placing predictable bits in weaker subchannels and CRC bits in stronger ones, this case improves broadcast signaling reliability.
- Polar-Code Interleaving Layout for Low-Latency Modulation
An odd-column interleaver cyclically reads polar-coded bits to cut latency while preserving modulation performance at higher orders.
- PBCH Polar Coding With Multi-Level Transform and Unequal Time Gaps
Multi-level scrambling, interleaving, and reordering let PBCH polar-coded bits span unequal time gaps to improve decoding reliability.
- PBCH Polar Coding With CRC Placement by Subchannel Reliability
Mapping CRC bits to high-reliability polar subchannels and predictable bits lower improves PBCH broadcast signaling reliability.
- PBCH CRC Bit Mapping with Cyclic Shift for Faster Frame Decoding
Cyclic shift carries PBCH frame bits while CRC placement blocks false checks, cutting terminal decoding attempts and delay.
- Non-Uniform QAM Constellation Mapping Near the Shannon Limit
Non-uniform constellation tables reshape QAM point spacing to narrow the Shannon-limit gap and improve BER and FER.
- Polar Coding Bit Mapping for Reliable Broadcast Signaling
Maps predictable bits and CRC bits to different polar-code reliability positions to improve broadcast signaling decoding accuracy.
- Non-Uniform Constellation Mapping for Broadcast Transmitters
Non-uniform constellation tables help broadcast transmitters close the Shannon-limit gap and improve BER/FER in high-order BICM modulation.
- Broadcast Receiver Modulation Using Non-Uniform QAM Constellations
Non-uniform QAM constellation mapping improves BER and FER in digital broadcasting while moving capacity closer to the Shannon limit.
- Radiation-Hardened Interleaved ADC Calibration With Three-Point Timing
Three-point timing calibration and a clamped watchdog improve interleaved ADC accuracy while limiting radiation-driven error propagation.
