In order to attain the improvement of a reliability and the high quality of optical-wireless communications, turbo coded systems are attracting attention. As the pulse modulation scheme for the optical-wireless turbo coded systems, hybrid pulse position modulation on-off keying signaling (HPOS) is superior to the other systems in an information transmission efficiency and bit error probability. The racing counters scheme having four counters in the optical-wireless turbo coded system using HPOS are proposed. In this paper, the bit error rate characteristics in consideration of the synchronization performance in the HPOS turbo coded system with the racing counters scheme are elucidated. As a result, the error floors are decided by the parameters of the racing counters.
