PAPR reduction of GFDM system using Parallel concatenation of LDPC codes

In this paper, we propose a peak to average power ratio (PAPR) reduction scheme for generalised frequency-division multiplexing (GFDM) systems based on parallel concatenation of low-density parity-check codes (PC-LDPC) codes. The proposed scheme maps the PC-LDPC codewords onto subcarriers to construct a symbol of channel coded GFDM. Then, these sub symbols are combined with subcarriers to form sym...
