Hardware realization of optical disc channel simulation

Through building up an optical disc channel model that is fit for realization on FPGA hardware and through analyzing noise,jitter and disturbance existing in optical disc storage systems,real-time continuous output of simulative RF signals for any two-level to four-level input data is realized.In the algorithm of simulation on hardware,a novel method of quadrupling frequency and an approach of looking up in ROM are proposed to realize the convolving calculation under 100Mbit high-speed condition.The simulation results show clear eye patterns,which verify the channel model set up.The results can be used as signal sources for following system designs,which greatly quickens the pace of developing and research.
