Abstract :
This paper presents a variation of circulant matrix based LDPC codes which allows more than one circulant identity matrix in a submatrix of the parity check matrix. The aggregated LDPC supports higher decoding throughput with small increase in datapath complexity. The construction algorithm, bit error rate (BER) performance, information update rule and the architecture for high decoding throughput are also presented
