Abstract
A first (receiver), for example, pseudo random binary sequence (PRBS) generator (6) is synchronized with a second identical PRBS generator (2) at a tramsitter by adding a PRBS (u(x)) to a data stream (w(x)). The data stream includes a known value at periodic intervals. The received data is framed (5) and thus the position of the known data values determined. The received data is sampled at these positions to produce a sequence of samples (s(x)) comprising a sampled version of the transmitter PRBS. The phase of the transmitter generator (2) is determined for the samples and the phase of the receiver generator (6) adjusted to correspond. (FIG. 1). Implementation with sequence generators other than binary sequence generators are also discussed.
