摘要：
The timing of a carrier signal is tracked in a receiver. The receiver receives a signal produced by a transmitter having a single frequency source which is used to generate a reference clock frequency and a carrier signal frequency, there being a fixed, predetermined relationship between the reference and carrier frequencies. In the receiver there is a single frequency source which is used to generate a reference clock frequency and a carrier reference signal frequency, there being a fixed, predetermined relationship between the reference and carrier reference frequencies. The fixed, predetermined relationship in the transmitter and the receiver is the same.
