Paper Abstract

Complex ternary matched filters (CTMFs) can be implemented optically using detour phase and a single ternary spatial light modulator or a Mach-Zehnder arrangement and two ternary signal light modulators. In this paper, we present the design of CTMFs that yield high signal-tonoise ratios (SNRs) and show with the help of simulation examples that their performance (in the sense of SNRs) is close to that of optimal matched filters.
