Abstract
A multiplication value decision unit () decides a multiplication value which is a positive value or a negative value corresponding to a bit value of each bit contained in a binary bit string constituting a scramble pattern generated in a pattern generation unit (). A multiplication processing unit () multiplies symbol data representing each symbol value in the symbol data string formed by the multinary symbol containing a predetermined pair of a positive value and a negative value having an identical absolute value, in the value area, by the multiplication value decided by the multiplication value decision unit (). Here, the multiplication processing unit () successively executes the multiplication between the symbol data for one symbol and the multiplication value decided corresponding to the bit value of the one bit contained in the scramble pattern until the number of symbols expressed by the symbol data string is reached. The present invention scrambles the data string by a simple operation and performs scramble by a simple processing even when the function channel content is changed.
