Abstract :
We have previously proposed Go-Back-i symbol automatic repeat request (GBi-ARQ) scheme appropriate to meteor burst communications. The GBi-ARQ scheme can achieve symbol-wise ARQ by using the Viterbi decoder for convolutional codes. In this paper, we propose a new carrier synchronization method appropriate to the GBi-ARQ scheme. The method can efficiently estimate carrier phase and frequency offset by using a pair of simple recursive equations for each survivor of the Viterbi algorithm.
