Abstract

In the new digital video broadcasting standard for satellite communications (DVB‐S2), 16‐ and 32‐ary amplitude‐phase shift keying (APSK) are recommended as complementary modulation schemes to 4‐PSK and 8‐PSK. For carrier phase recovery with feedback loops, decision‐directed (DD) and non‐data‐aided (NDA) detector algorithms are basically applicable. In some recent papers, however, a hybrid NDA/DD solution has been suggested for this purpose, although not analysed in detail. Motivated by this observation, the hybrid algorithms are investigated in this paper in terms of detector characteristic (S‐curve) and jitter variance as the main figures of merit in this respect, with an additional design parameter introduced for optimisation. For comparison reasons, results for power‐law and monomial‐based Viterbi and Viterbi (V & V) trackers, as classical NDA solutions, are derived as well. Copyright © 2009 John Wiley & Sons, Ltd.
