SIGNAL PROCESSING METHOD AND APPARATUS FOR STORAGE SYSTEM INTERFACE CIRCUIT

WIPO Patent Application WO/2023/193587

A1

The present application relates to a signal processing method for a storage system interface circuit. The signal processing method comprises: preprocessing a received signal to obtain an input signal; removing a weighted feedback signal from the input signal to obtain an output signal, wherein the weighted feedback signal is provided by a finite length unit impulse response (FIR) filter in a feedback path; making a decision on the output signal on the basis of a predetermined base signal to generate a digital output signal; weighting the digital output signal by means of a filter coefficient matrix of the FIR filter to obtain a weighted feedback signal; comparing the output signal with a reference signal to generate an error signal; and determining, according to the correlation between the digital output signal and the error signal, a set of optimized filter coefficients of the filter coefficient matrix of the FIR filter and the reference signal to minimize intersymbol interference introduced into the received signal by means of the transmission characteristics of a signal receiving link.
