Modulo-N code is a lossy compression algorithm used to compress correlated data sources using modulo arithmetic. ==Compression== When applied to two nodes in a network whose data are in close range of each other Modulo-N code requires one node (say odd) to send the coded data value as the raw data ; the even node is required to send the coded data as the . Hence the name Modulo-N code. Since it is known that for a number K, at least bits are required to represent it in binary. So the modulo coded data of the two nodes requires totally . As we can generally expect always, because . This is the how compression is achieved. A compression ratio achieved is . 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Modulo-N code」の詳細全文を読む スポンサード リンク
