Performance analysis of the undersampled frequency shift ON–OFF keying (UFSOOK) protocol, frequently used in visible light communication, is provided. Data transmission is modeled as a measurement process, and the analysis of the underlying measurement channel and the possible error sources reveals important performance properties of the protocol itself. The theoretical bit error rate, as a function of the receiver camera’s sampling properties, the frequency error between the transmitter and the receiver, the measurement noise, and the parameters of the protocol, is derived. A measurement process is also proposed, with which the theoretical results are validated.
