Impulse Noise Mitigation via FEQ and DEC Adaptation Freeze

The patent applies preliminary action by detecting impulse noise before it can corrupt system parameter adaptation. The controller monitors signal characteristics and identifies impulse noise occurrences in advance, then proactively freezes parameter adaptation to prevent noise-induced deviations from accumulating. This preventive approach maintains reliable communication by stopping the adaptation process before harmful effects can manifest.

The patent introduces an intermediary control mechanism that mediates between the adaptive parameter adjustment process and the impulse noise environment. The controller acts as an intermediary by monitoring signal quality and controlling when parameter adaptation should occur or be frozen. This intermediary control protects receiver operations from strong impulse noise by preventing adaptation during noisy periods, while still allowing normal adaptation during clean signal conditions.

The patent implements periodic action by alternating between parameter adaptation and freezing based on detected impulse noise conditions. During noise-free periods, parameter adaptation proceeds to optimize communication efficiency. When impulse noise is detected, adaptation is temporarily frozen to maintain parameter accuracy. This periodic switching between adaptation and freezing states allows the system to achieve both high communication efficiency and accurate parameter estimation.
