Error Correction/Detection Using Trellis Coding TRIZ Cases
- Trellis-Coded Symbol Ordering in Higher-Order Constellations
Strategic ordering of constellation subsets cuts DFE tap variability and decoder hypotheses while preserving higher-order modulation efficiency.
- Transform Coefficient Quantization Using Trellis State Contexts
Partial syntax elements drive trellis quantizer states and context models, improving transform coefficient coding efficiency with lower complexity.
- Constant-Envelope Trellis Modulation for Power-Efficient QAM
A base symbol plus perturbation signal keeps the transmit envelope constant, improving QAM power efficiency without linear amplifiers.
- Wireless Uplink Waveform Segmentation for Lower PAPR
Phase-domain overlap-and-add across waveform segments lowers uplink PAPR and symbol interference for more efficient RF transmission.
- TCM Decoder Region Decision for High-Order QAM Complexity
Region-based constellation decisions cut Euclidean distance calculations in high-order QAM TCM decoding while preserving Viterbi inputs.
