| Abstract: | A decision feedback partial response maximum likelihood(PRML) for super-resolution media was developed.Decision feedback is used to compensate for nonlinear distortion in the readout signals of super-resolution media,making it possible to compensate for long-bit nonlinear distortion in small circuits.A field programmable gate array(FPGA) was fabricated with a decision feedback PRML, and a real-time bit error rate(bER) measuring system was developed.As a result,a bER was achieved with an actual readout signa... |
