DVB-S2 LDPC DecoderDecoder, The LdpcDecoder, LdpcCorrection, Forward Error
The LDPC decoder decodes the deinterleaved soft bit values and generates hard decisions. The BCH decoder works on these hard decisions to create the final estimate of the received frame. The second part of the for-loop collects performance measurements such as the bit error rate and a scatter...
TheDVB-S2 BCH Decoderblock decodes and recovers messages from a Bose-Chaudhuri-Hocquenghem (BCH) codeword according to the Digital Video Broadcast Satellite Second Generation (DVB-S2) standard[1]. The block accepts low-density parity-check (LDPC) decoded codeword data bits and a stream of cont...

LDPC-Dec-DVBS2 is an RTL model in the VHDL hardware description language of a LDPC decoder for the digital video broadcast DVB-S2 standard. LDPC-Dec-DVBS2 is implemented as a synthesizable VHDL model. It is capable of processing all specified code rates of the DVB standard. This model is...
Previous studies that used Graphics Processing Units (GPUs) to decode Low Density Parity Check (LDPC) codes for DVB-S2 employed inter-codeword parallelism and/or Turbo Decoding Message Passing (TDMP) to achieve high throughput. By converting the LDPC parity check matrix into a quasi-cyclic struct...
The DVB-S2 LDPC decoder is synthesized for use in the Xilinx Virtex-II Pro XC2VP100 FPGA, which is the same FPGA used in [9]. For simplicity, in the remainder of this paper, the decoders presented in Section 3 are referred to as the 360-FU decoder and 180-FU decoder, and the 180...
