We demonstrate that crosstalk caused by matched filtering can be suppressed by designing a header recognition filter in the header recognition unit based on optical correlation processing. The header recognition filter is designed using a technique of a multiple-object discriminant filter (MODF). Results of preliminary experiments show that the designed header recognition filter can suppress crosstalk. The peak intensity ratio of correlation signals of a target header signal to those of nontarget ones is higher than $1.48:1$ in the case of 4-bit header signals. The number of discriminable header signals could markedly increase using the designed header recognition filter.
