Outline of Final Research Achievements

Symbol-pair read channel has been proposed as a model high density storage system, and is expected as an economical read write model. In this research, various results on performance analysis have been obtained. In this report, computing algorithms for minimum symbol-pair weight and symbol-pair weight distribution as well as theoretical analysis of them are presented. For the b-symbol read channel which is a generalization of symbol-pair read channel, a trade off between the minimum b-symbol weight and the code rate is also analyzed.
