Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a transmission rate information encoding/decoding apparatus and a method for a code division multiple access mobile communication system.

SOLUTION: The encoding apparatus for the communication system includes: a one-bit generator for generating a sequence of the same symbols; a base orthogonal sequence generator for generating a plurality of base orthogonal sequences; a base mask sequence generator for generating a plurality of base mask sequences; and an arithmetic part for receiving transmission rate information bits containing a first information portion indicating conversion into a biorthogonal sequence a second information portion indicating conversion into an orthogonal sequence and a third information portion indicating conversion into a mask sequence combining an orthogonal sequence selected by the second information portion in the base orthogonal sequence a biorthogonal sequence constituted into the combination of the selected orthogonal sequence and the same symbol selected by the first information portion and a mask sequence selected by the biorthogonal sequence and the third information portion and generating the transmission rate information sequence.
