| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The combination of the low-density parity-check (LDPC) code and the belif-propagation (BP) decoding algorithm exhibits a good decoding performance. Now error correction via LDPC code is applied for high speed wireless channel, wired channel and magnetic recording systems. To evaluate the correcting capability for burst erasure, analysis for the LDPC code ensemble has been employed. First, this analytical method evaluates the minimum span of the stopping set, and then, calculate the critical minimum span rate which expresses the rate of the correctable burst erasure for the code length. In this paper, we formulate more accurate critical minimum span rate by using minimum stopping set for the standard Tanner graph ensemble. We then apply it to evaluate the critical minimum span rate for the LR Tanner graph ensemble, which is a combined graph ensemble with a good correcting capability for burst erasure. |
