METHOD OF SYNCHRONISING DATA |
摘要 |
A method of synchronising data in a communications system (10) comprises the steps of: (a) Generating at transmitting means (20) a composite signal comprising a serial stream of data partitioned in one or more frames; (b) transmitting the composite signal through communicating means (50) to receiving means (30); (c) generating multiphase clock signals; (d) comparing the composite signal received at the receiving means with each of the multiphase clock signals until either sustained coincidence therebetween is achieved or sustained non-coincidence is achieved, thereby synchronising the receiving means to bit boundaries in the composite signal and to one or more of the clock phase signals; (e) correlating one or more bit templates at the receiving means with one or more corresponding bit templates in the composit e signal received at the receiving means to determine where frames start in th e composite signal, thereby synchronising the receiving means to the one or mo re frames in the composite signal.
