Frequency-Modulated Carrier Systems TRIZ Cases
- Chirp Modulation Frequency Control for IoT Interference Suppression
Transmission device sets distinct frequency change rates for chirp modulation to differentiate signal types.
- In-Line Modem Security Intermediary for Legacy Signal Protection
An in-line system processes legacy modem signals via real-time configuration, mitigating eavesdropping and jamming attacks on communication channels.
- Dual Core Modem Multi-Channel Signal Processing
Segmenting modem functions across two CPU cores increases network bandwidth without adding hardware components or increasing device complexity.
- OFDM Receiver Frequency Offset Estimation via Karhunen-Loeve Approximation
Karhunen-Loeve approximation of log-likelihood functions estimates fractional frequency offset in OFDM receivers using pilot signals.
- TPM Sensor Frequency Deviation Adjustment via Switchable Capacitors
Switchable capacitors in a phase locked loop adjust frequency deviation, resolving in-band noise and narrow band receiver compatibility issues.
- Co-channel Jamming Detection in FM Radio Signals
A dedicated sensor detects co-channel interference by analyzing positive and negative noise peaks in symmetric passband FM radio signals.
