Abstract

The structure of the Physical Layer Frame (PLHFRAME) is flexible for DVB-S2 system. At the receiver, it is critical for decapsulating the frame design. By further analyzing the structure of the PLHFRAME, we find some useful properties and also introduce some optimizations into the algorithm. The algorithm is based on a first order Reed-Muller (RM) code to achieve decapsulating the frame. The design scheme has implemented on Xilinx Virtex xc4vlx25 FPGA. Hardware test results show that the new scheme can be achieved under large carrier frequency offset (as large as 5MHz at 25MSps) and low SNR threshold of-2.5dB.
