Abstract
A signal quality measurement system includes a transmitter for transmitting a test signal to a receiver and a device for storing a copy of the test signal at the receiver. The similarity between the stored copy of the test signal and the signal received at the receiver is measured to determine reception quality. The receiver also includes a device for selecting a sequence of different synchronization patterns directly from the stored copy of the test signal, for determining, from said received signal, a sequence of signal segments that best matches the synchronization pattern sequence and for synchronizing the received signal with the signal segment sequence, thereby synchronizing the received signal with the stored copy of the test signal.
