Abstract:
It is known that a CRC (cyclic redundancy check)-concatenated polar coding scheme with successive cancellation list (SCL) decoding can signicantly enhance the error rate performance of the polar code with successive cancellation decoding. This advanced decoding method for the CRC-concatenated polar coding scheme is also called the CRC-aided SCL decoding method. In this research, the CRC-concatenated polar coding schemes are designed for multi-track recording with two-dimensional (2D) run-length limited constraints. We evaluate the error rate performances of the two-dimensional magnetic recording (TDMR) systems with the proposed coding and 2D partial response equalization schemes using bit-patterned media. As a result, it shows that the block error rate (BER) performances of the multi-track recording systems with CRC-aided SCL decoding are superior to that of the single recording systems with the conventional high rate binary coding schemes.
