Design and FPGA implementation of trellis coded modem based on DVB standard

A new high performance LDPC code for DVB-S2 - Spectrum: Concordia University Research Repository

Documentation Help Center Documentation. The example uses communications System objects to simulate a transmitter-receiver chain that includes LDPC encoding and decoding. LDPC codes, invented by Gallager in his seminal doctoral thesis in , can achieve extremely low error rates near channel capacity by using a low-complexity iterative decoding algorithm [ 2 ]. The channel codes for DVB-S. Depending on the transmission mode, DVB-S. The example collects the error rate at the demodulator, LDPC decoder, and BCH decoder outputs, determines the distribution of the number of iterations performed by the LDPC decoder, and shows the received symbol constellation.

DVB-S.2 Link, Including LDPC Coding in Simulink

Masters thesis, Concordia University. Around three decades after the invention of this code, researchers returned back their attention to it and tried to make some significant improvements in complexity. As the result, the LDPC codes were widely considered in the next generation error correcting codes in telecommunication systems. The features of the above mentioned code allow a transmission near the Shannon limit.
