US Patent 11038549 Receiver noise loading for control loop stability

A receiver is configured to generate a digital signal representative of data conveyed by a communication signal detected at the receiver, and to apply digital signal processing to the digital signal, thereby generating a processed signal. The receiver is further configured to determine a relative noise estimate for the processed signal, and to load an amount of digital noise into the digital signal processing based on a difference between the relative noise estimate and a target. As a result of the digital noise loading, improved stability of at least one control loop in the receiver may be achieved.
