Frame Error Detection Performance of Optical-Wireless Advanced Framed-DOOK System

As a high transmission rate binary modulation scheme, an advanced framed-DOOK (AF-DOOK) system, which can solve the problems with the conventional OOK system and the conventional framed-DOOK system such as the performance degradation by background noise and synchronization slip has been proposed by authors. The AF-DOOK system is the advance of the conventional framed-DOOK system by extending the synchronization signal from 1-bit to 2-bits. The AF-DOOK system has a frame error detection method which the conventional framed-DOOK system does not have. In this paper, the frame error detection performance by 2-bits synchronization signal of the AF-DOOK system is investigated. The theoretical formulas to assess frame error detection performance are derived and evaluated; the frame error detection probability, the frame error undetected probability, and frame error misdetection probability. Consequently, it is indicated that the frame error detection method of the proposed AF-DOOK system is practically effective under the optical-wireless channel with scintillation and background noise.
