- Abstract
- In this paper, we present efficient carrier phase estimating algorithms collaborate with a turbo code decoder for mobile broadband satellite DVB-RCS systems. Estimation of the carrier phase is based on soft information of transmitted symbol provided by iterative turbo decoder. We investigate performance of external single estimator and internal multiple estimator in the PSP (Per Survivor Processing) manner over AWGN channel. For phase estimation, the LMS (Least Mean Square) scheme is considered. For decision of transmitted symbol, three different APP-based methods are also compared. © 2006 IEEE.
