BIT ASSIGNMENT ASSESSMENT DEVICE, BIT ASSIGNMENT ASSESSMENT METHOD, AND PROGRAM

摘要

A bit assignment estimating device that is capable of accurately estimating bit assignment of a payload with fewer division patterns than those in related art is provided. The bit assignment estimating device includes: a receiving unit that receives communication data; a block generation unit that divides a payload of received communication data so as to generate a plurality of blocks; a unit block bit assignment estimation unit that estimates bit assignment of a block to be any one of a fixed value type, a status value type, and a continuous value type; a block concatenation unit that concatenates a block, which is adjacent to either of a block or a concatenation block which is estimated to be the continuous value type at a higher-order bit side, to the block or the concatenation block which is estimated to be the continuous value type when the block adjacent is estimated to be the status value type or the continuous value type; a concatenation block bit assignment estimation unit that estimates whether the concatenation block is the continuous value type or not; and a block separation unit that separates an immediately-close-concatenated block from a corresponding concatenation block when the concatenation block is estimated not to be the continuous value type.
