Coded SC-FDE system over impulsive noise channels

Single carrier transmission with cyclic prefix (SC-CP or SC-FDE), has lower PAPR (peak to average power ratio) problem and requires smaller backoff of amplifier than orthogonal frequency division multiplexing (OFDM) technique. In order to combat impulsive noise under power limited channels, we apply regular LDPC (low density parity check) codes and propose a simplified decoding method. Also We compare the system with and without CP combining under uncoded and coded case. Simulation results show that the proposed method is effective under impulsive noise channels.
