In this paper, we implement the robust demodulator for mobile broadband satellite internet access systems. Especially, in order to achieve the good synchronization under very low SNR, a large frequency offset, and Doppler frequency offset with constraints of mobile satellite communication, we introduce the efficient carrier freq. offset estimating algorithm and the carrier phase estimating algorithm to be integrated into the channel decoder of a Turbo coded modulation for mobile DVB-RCS system. The proposed techniques can fulfill the stringent up-link link budgets at Ka band by operating at very low SNR.
