Abstract

An approach concerned with low-density parity-check (LDPC) codes that have high performance decoding capability. With help of Alamouti STBC (space time block codes) which is concatenated with LDPC, it has been deduced that, the so constructed model has better performance than the existing in terms of Bit Error Rate (BER). A soft decision based decoding algorithm shows best performance than other decoding algorithms. Thus, for better performance Log-domain decoding of LDPC codes is implemented.
