Combined Modulated Pulse Demodulation TRIZ Cases
- Phase Rotation Demodulation for Overlay Symbol Detection
Rotating chip phase transitions in one direction enables robust overlay symbol detection without degrading the host waveform or spectrum.
- Carrier Signal Separation for Extracting TM-Modulated Signals
Separates TM signals from a shared carrier by reconstructing and subtracting the first modulation, enabling mixed modulation without interference.
- Phase-Based Signal Demodulation for Multi-Format Receiver Simplification
Phase-difference demodulation with shared ADC, IQ, and FFT blocks recovers multiple signal formats while reducing receiver hardware complexity.
- Hierarchical RF Modulation Layers for Rate-Reliability Tradeoffs
Hierarchical modulation assigns data to RF layers by reliability, improving bandwidth use while balancing high data rate and signal integrity.
- Matched Filter Training Sequence Detection Under Blind Channel Offsets
A rearranged matched filter detects training sequences under blind channel conditions while reducing computation and estimating frequency and timing offsets.
- Orthogonal Error Compensation in Communicating Apparatus
Separate feedback paths distinguish modulator and demodulator errors, resolving ambiguity while reducing circuit complexity.
- Spectral Notch Modulation for Navigation and Communication
Spectral notch modulation encodes data by nulling frequency bins, enabling simultaneous navigation ranging and communication without increasing bandwidth.
