Abstract: A light communication system, receiver, and method for synchronizing a receiver with a transmitter so as to decode a data input stream transmitted by the transmitter and received at the receiver. The method includes: receiving a data input stream at a receiver, the data input stream having a first data rate that is set based on a transmitter clock rate; generating a wave; obtaining a phase error between the data input stream and the generated wave; determining a synchronized clock rate by using the phase error to adjust the frequency of the generated wave so as to match the frequency of the generated wave to the transmitter clock rate of the data input stream; and using the synchronized clock rate to decode the data input stream so as to obtain data encoded in the data input stream.
