| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | It has been pointed out that high-density storage media, e.g., bit patterned media recording, and high-speed data transfers suffer from insertion/deletion errors caused by mis-synchronizations, as well as random errors induced by noises and signal interferences. Therefore, it is important to construct efficient insertion/deletion/substitution (IDS) error control codes. Existing IDS error control codes generally assume that insertion/deletion errors occur statistically independently, while in actual communication channel, it is natural to consider that the insertion/deletion errors are caused by accumulation of mis-synchronizations. To model such type of insertion/deletion errors, this paper defines an IDS channel in which the errors are expressed by $t/m$-bit insertion/deletion errors. An existing marker-based IDS error correcting code is applied to the IDS channel, and the decoded bit error rate (BER) is evaluated by simulation. The results show that the BER cannot be reduced sufficiently by straightforward application of the code, while the BER can be lowered by imposing a slight difference of clock periods between transmitter and receiver. |
