Abstract

In the frame of digital video broadcasting by satellite - second generation (DVB-S2), a faster-than-Nyquist (FTN) system based on turbo equalization and low-density parity-check (LDPC) codes is proposed. Truncated maximum a posteriori (MAP) and minimum mean square error (MMSE) equalizers provide a reduced complexity implementation of the FTN system. On the other hand, LDPC codes allow us to demonstrate attractive performance results over an additive white Gaussian noise (AWGN) channel while increasing spectral efficiency beyond the Nyquist rate up to 60 % and keeping a complexity comparable to a current DVB-S2 modem.
