MPRML detection for the readouts of photometric multi-wavelength optical disks

Based on the readout and crosstalk analysis, a kind of multi-channel partial response maximum likelihood (MPRML) detection method which is suitable for photometric multi-wavelength optical disks has been brought forward, the PR mode and parameters have been discussed, and the optimal solution of the method has been given in the paper. Matlab simulation shows that the MPRML method is useful to improve BER performance and the optimal solution is proper. The experiments on the FPGA-based development board also show that MPRML is applicable for photometric multi-wavelength optical disks.
