Channel Estimation TRIZ Cases
- Wideband Impulse Response Reconstruction From Narrowband Subbands
Multiple narrowband analog observations are combined with alias-based subband expansion to reconstruct a wideband impulse response for DPD equalization.
- NR Zone-Based Signaling for Low-Latency Multicast Throughput
Geographic zone mapping lets UEs select relevant channel parts, improving multicast reliability, latency, and resource use in NR.
- Adaptive Channel Estimation Control for Fast-Fading Wireless Links
Correlation-based channel statistics adapt averaging to fast or slow fading, improving demodulation accuracy as propagation conditions change.
