Multiple Modulation Transmitter/Receiver Arrangements TRIZ Cases
- Vendor-Specific PPDU Format for Wi-Fi 8 Interoperability
A Physical Layer Protocol Data Unit format includes a vendor-specific signal field to carry proprietary data.
- RF Receiver With Shared Demodulator for Multi-Scheme Detection
A radio-frequency receiver uses a single shared demodulator to detect multiple modulation schemes concurrently.
- Turbo Receivers for MIMO Underwater Acoustic Communications
Iterative soft-decision adaptation reduces multipath interference and processing delay while maintaining detection reliability in noisy environments.
- Wireless Consumable Chip System for Printer Cartridge Upgrades
A consumable chip system uses a wireless transceiver module to establish communication with printer devices without physical contact.
- ATC Overlay Modulation for Data Throughput
Overlay modulation embeds additional data within existing ATC signals using phase shift keying, doubling capacity without legacy interference.
- COFDM Overlay Modulation Using Phase and Amplitude Offsets
Applying phase and amplitude offsets to QPSK symbols enhances data transmission capacity without degrading resistance to multi-path effects.
- Modem Modulation Mode Auto-Adjustment via Indication Frames
First modem transmits indication information via data frames so the second modem adjusts its modulation mode, eliminating manual configuration complexity.
- Processing Circuit Phase Control for Radio Noise Reduction
A processing circuit generates a phase-shifted clock signal to synchronize analog-to-digital conversion.
- Embedded Clock Signal Synchronization for Radar Phase Alignment
Embedding frame start signals within clock signals eliminates PCB delay variations that cause phase errors, ensuring precise angular resolution.
- Sub-terahertz Receiver Using Analog Projection and Joint Demodulation
A receiver projects modulated signals onto an analog Fourier base for joint demodulation.
