Trained States Equalizer in a Read Channel - A simplified explanation of the abstract

This abstract first appeared for US patent application 17946399 titled 'Trained States Equalizer in a Read Channel

Simplified Explanation

The abstract describes a system for states equalization of a digital data signal in preparation for a soft output detector. The system includes a states equalizer that filters signal values through finite impulse response filters to generate state values for a target signal value, which are then used to determine probabilities for possible states in a decision matrix for the soft output detector.

• The system includes a states equalizer that filters signal values through finite impulse response filters.
• The filters are configured to generate state values for a target signal value.
• Each filter corresponds to a potential state of the target signal value.
• The state values are used to determine probabilities for possible states in a decision matrix for a soft output detector.

Original Abstract Submitted

Example systems, read channels, and methods provide states equalization for a digital data signal in preparation for a soft output detector. The states equalizer determines a set of signal values from the digital data signal and filters the set of signal values through a set of finite impulse response filters configured to generate a set of state values for a target signal value, where each filter corresponds to a potential state of the target signal value. Based on the state values, a set of probabilities for possible states is determined and used to populate a decision matrix for a soft output detector.
