Abstract
This paper presents a simple method in designing a parity matrix of low density parity check codes. According to its use the use of arithmetic sequence is ideal for high rate code with no existing of cycle 4. The design is applicable to array code, modified array code, and quasi cyclic code. Upon the investigation, the designed code has delivered a similar BER-SNR performance when compared with that of more complicate designed matrices.
