摘要 |
<p>The controller receives at least a first pseudo-noise digital sequence (21) and periodically a second digital sequence (22) which is the inverse of the first sequence and is obtained according to time symmetry. Frequency and time synchronisation is performed using synchronisation packets which are inserted into a main signal. Each synchronisation packet contains the first sequence and then the second sequence. The signals received at the receivers are equalised and the sequences input to registers. When a complete set of data is received, the sequence and its inverse can be detected. <IMAGE></p> |
