Synchronisation detection in an M-ary PSK system with a rate-selectable punctured convolutional code

摘要

The authors propose an efficient algorithm for detecting synchronisation in a Viterbi decoder. By monitoring the 'back-traceability' between two trellis states with the minimum metric at adjacent time units, over a specified span, the proposed algorithm can efficiently detect synchronisation. Experimental results confirm the efficiency of the proposed algorithm.
