A 54 MHz BiCMOS Digital Equalizer for Magnetic Disk Drive
BiCMOS Digital Equalizer Magnetic Disk Drive
2015/8/14
Until recently, only analog bit-detectors have been avail-able for high-speed magnetic-disk recording. Because of high data-rates and strict power consumption limits, digital approaches have been deem...
Implementation Efficient Nonlinear Equalizer Based on Correlated Digital Backpropagation
Optical communications Coherent communication Phase modulation
2011/5/26
One stage per span is commonly considered as the lower boundary for implementation complexity of nonlinear equalizer based on digital backpropagation. The proposed method overcomes this boundary and i...
A new ultra-high sensitivity, low-power optical receiver based on a decision-feedback equalizer
