Performance of NB-LDPC and DBTC Codes with Channel Estimation and SNR Mismatch

摘要：

This paper compares the robustness of Non-Binary LDPC and Duo-Binary Turbo Code schemes against impairments in the estimation of the channel coefficients, and the noise power. This study considers both types of mismatches separately and jointly. The scenario of simulation also takes into account the distortions introduced by a High Power Amplifier (HPA) and the Inter-Carrier-Interference (ICI) caused by a mobile channel. The communication system under analysis is the OFDM-based WINNER wireless model. The results show that Non-Binary LDPC codes provide even better performance than DBTC in the case of non perfect channel knowledge.
