LSE and MSE optimum partition-based FIR-IIR deconvolution filters with best delay

The partition-based finite impulse response-infinite impulse response (FIR-IIR) filters where the channel zeros are partitioned into two regions is presented. Results reveal that FIR-IIR best delay inverse filters are less sensitive to the estimation errors compared with the IIR Wiener filters, and they perform better than the FIR Wiener filters.
