Abstract
To overcome large carrier frequency offsets in burst demodulation of quadra ture amplitude modulation, a new Viterbi-type algorithm coupled with a data -aided frequency estimation is developed. This algorithm can quickly acquir e carrier offset, then remove it during the process of demodulation. Its pe rformance is confirmed as approaching that of coherent demodulation, with l ittle loss of short pilot data.
