概要

We propose an improved detection method that concurrently adjusts the coefficients of equalizer and reference branch values in Viterbi detector. For the estimation of asymmetric channel characteristics, we exploit sync patterns in each data frame. Because of using the read-only memory (ROM) table to renew the coefficients of equalizer and reference values of branches, the complexity of the hardware is reduced. The proposed partial response maximum likelihood (PRML) detector has been designed and verified by VerilogHDL and synthesized by Synopsys Design Compiler with Hynix 0.35 μm standard cell library.
