Abstract
In the new digital video broadcasting standard for satellite communications (DVB-S2), 16-ary amplitude-phase shift keying (APSK) is recommended as modulation scheme. For carrier phase recovery with feedback loops, deci-sion-directed (DD) and non-data aided (NDA) detector algo-rithms are basically applicable to 16-APSK schemes as well. In a recent paper, however, a hybrid NDA/DD solution has been suggested although not analyzed in detail. Motivated by this fact, the latter is investigated in terms of detector characteris-tic (S-curve) and jitter variance as the main figures of merit in this respect. For comparison purposes, results for power-law and monomial-based Viterbi and Viterbi trackers, as classical NDA solutions, are also included.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
