Abstract
A receiver for receiving a signal, the signal conforming to a protocol such that the signal comprises a synchronising portion and a data portion, each portion comprising pulses located in respective time slots, the time offsets between successive time slots being defined by the protocol, the receiver comprising: a detector configured to detect a first pulse and a second pulse of the synchronising portion; a comparison module configured to compare the time offset between the first and second pulses to a corresponding time offset defined by the protocol so as to determine the relationship between the detected time offset and the corresponding time offset; a determination module configured to determine expected times of arrival of the time slots of the data portion using the determined relationship and the time offsets defined by the protocol; and a data reader configured to read data conveyed in the data portion at the expected times of arrival.
