  Abstract

This paper presents an efficient demapper architecture based soft-decision using the phase-section for Digital Video Broadcasting via satellite, Second Generation (DVB-S2). To achieve the satisfactory performance under a very low SNR conditions with the efficient hardware resource utilization, we propose a simple soft-decision demapper architecture using comparators to compare the phase of symbols and memories. The proposed architecture can decrease about 81% of the hardware resource, satisfying the BER requirements of DVB-S2. It has been thoroughly verified with an FPGA board and R&SⓡSFU (Rohde&Schwarz SFU-K108) broadcaast test equipment.
