Hybrid LDPC and STBC Algorithms to Improve BER Reduction in OFDM Systems

Abstract

THE SEARCH for a good coding algorithm is motivated by the fact that various communication channels require their optimal performance. Orthogonal Frequency Division Multiplexing (OFDM) WiMAX transmission system is used over different fading channels with adaptive modulation and coding (AMC). The computer simulation result shows improved error-correction capability in LDPC codes and STBC codes. The paper proposed hybrid LDPC and STBC method and proved its good bit error performance.
