Paper Abstract

Based on the analysis of the MIL-STD-1773 data bus modulation scheme, two optical modulation schemes are proposed for designing this kind of data bus, namely, partial tri-level Manchester II bi-phase coding (PTMBC) and extended Manchester II bi-phase coding with beginning-stopping flags (EMBC-BSF), which can efficiently solve the problem related to three outputs at a MIL-STD-1773 optical receiver with low complexity. Then we focus on the analysis of error probability and optical receiver sensitivity for MIL-STD-1773 data buses with three modulation schemes of Manchester II bi-phase coding, PTMBC , and EMBC-BSF. The results show that both the PTMBC and EMBC-BSF modulation schemes have almost the identical and worse receiver sensitivity than that of the Manchester bi-level coding by ~3dB.
