Amplitude Demodulation TRIZ Cases
- Adaptive Signal Cancellation for Weak-Signal Receiver Isolation
Adaptive cancellation uses error-driven parameter updates to remove strong interference and recover weak signals in dynamic communication links.
- Adaptive Receiver Cancellation for Strong and Weak Signal Isolation
Adaptive parametric cancellation uses error feedback to suppress strong interfering signals and recover weak-signal data in changing links.
- Blind IQ Balance Circuit for Direct Conversion Receivers
Continuous blind IQ balancing and adaptive NZIF selection reduce DC offset, bit errors, and adjacent channel interference in direct conversion receivers.
- FIR Filter Magnitude Design for Global Minimax Optimality
A two-step autocorrelation and spectral factorization approach gives FIR filters globally minimax-optimal magnitude response for non-linear phase designs.
- Data-Dependent Equalizer Circuit for NRZ Noise Filtering
NRZ-specific noise prediction filters and equalizers cut read errors, improving BER/SFR without slowing data throughput.
- Periodic Timing Reference Detection Against Noise Spikes
Correlating and accumulating delayed signal copies helps distinguish valid periodic references from noise spikes, improving LTE detection sensitivity.
- Feedback Signal Delay Estimation Using Correlation Differences
Difference-based correlation estimates feedback-signal delay at identical timings, improving distortion compensation with lower circuit complexity.
- Periodic-Oscillation RF Receiver for Low-Emission Signal Detection
Periodic oscillator activation and threshold-based correlation cut spurious emissions and power use while preserving robust RF symbol detection.
- Wideband Receiver Downconversion Switching Under Interference
An interferer detection block enables extra downconversion paths only when needed, balancing wideband receiver rejection and power use.
- Single Clock CDR for Low Power High Speed Data Recovery
A single low-power clock system adjusts sampling timing via time-amplitude analysis of known bit patterns to improve data recovery accuracy.
