On Pilot-Symbol-Assisted Carrier Synchronization for DVB-S2 Systems

By Alan Barbieri and Giulio Colavolpe

Abstract

Abstract—We consider the problem of carrier synchronization in future 2nd-generation satellite digital video broadcasting (DVB-S2) receivers. In this scenario, this task is made harder by the complexity constraints, related to the use of consumer-grade equipment. Making use of the distributed pilot symbols of the DVB-S2 standard, low-complexity techniques for fine frequency estimation and for detection in the presence of a strong phase noise, typical of consumer-grade equipment, will be proposed. The performance of the described algorithms will be analysed in detail through computer simulations. Index Terms—Carrier synchronization, DVB-S2 systems, iterative detection and decoding, phase noise, satellite communications. I
