ABSTRACT:
To each bit time of a data block, there is associated a counter which is incremented or decremented in accord with the congruence or non-congruence of the c bit sequence associated with the respective counter (for example, the first bit of the c bit sequence). The counters are initialized to an optimum non-zero value and after receiving a number of blocks of data, each containing one sync symbol, the synchronization is determined from the relative content of the counters.
