Abstract
This paper presents the application of a random number table for the parity check matrix construction of irregular low-density parity check (LDPC) codes. The performance of the constructed codes was tested in bit-patterned media recording channels. The obtained performance of the proposed codes was compared with that of the existing codes. The simulation results show that, at a block length of 4110 bit and code rate of 0.9, the proposed LDPC code yields better performance than the existing ones, especially at high signal-to-noise ratio scenario. © 2013 IEEE.
