Multiplex Multicode TRIZ Cases
- Edge-Group Spreading for Low-Interference Data Transmission
Orthogonal spreading on edge sequence groups cuts inter-subband interference and out-of-band leakage without changing occupied bandwidth.
- Spread-Spectrum Video Transport With QAM for Signal Resilience
Attenuation, reflections, and aggressor signals degrade video links; combining SSVT encoding with QAM improves density and noise resilience.
- CDMA Transmitter Orthogonal Codes for Railway Interference
Synchronized orthogonal CDMA spreading codes enable simultaneous data transmission through powerline channels.
- Impulse Response Filter for CDM Signal Measurement Accuracy
Variable weighting of accumulated signal bursts reduces correlation between sequential measurements, improving user input detection accuracy.
- Combined Demodulator and Despreader Circuit for RF Systems
A combined demodulator and despreader circuit processes in-phase and quadrature signals using analog correlation to recover data symbols.
