Multiple Modulation Transmitter/Receiver Arrangements TRIZ Cases
- Managed Time Division Duplex Baseband Signaling for Satellite Terminals
A managed time division duplex baseband signaling protocol coordinates transmission periods between indoor and outdoor satellite units.
- Hybrid FQAM Modulation for Wireless Signal Transmission
A hybrid FQAM modulation scheme transmits signals using active tones to optimize spectral efficiency in wireless communication systems.
- C-RNC Local Cell Capability Determination via Default IUB Bearer
A controlling radio network controller determines local cell support capability by receiving node B capability information and applying a default separate IUB transport bearer assumption.
- Uplink Packet Triggering in Wireless LANs
Trigger frames allocate resource units to high-efficiency stations, resolving bandwidth utilization conflicts with legacy device compatibility.
- Carrier Signal Extraction from Modulated Signals
Extract transpositional modulation signals from combined carriers by detecting center frequency and modifying local oscillator, resolving separation difficulty.
- Dynamic Modulation Profile Adjustment for Interference Mitigation
Nodes monitor packet errors to switch modulation density, reducing interference impact on communication reliability.
- Interference Suppression for Mixed Modulation Signals
Phase rotation aligns interfering signals to generate specific filter coefficients, suppressing co-channel interference in mixed modulation environments.
- Infrastructure Equipment Cepstrum-Based SINR Estimation
Infrastructure equipment estimates signal-to-interference-and-noise ratios across resource units and produces a cepstrum for transmission.
