Abstract
A spreading process is performed with a spreading code assigned to each user and a spreading code assigned according to an attribute, and the resultant signal is modulated on the transmitter side. On the receiver side, a transmitted signal, modulated in the above manner, is subjected to a despreading process with the attribute-oriented spreading code from a reception spreading code generator, the resultant signal is subjected to despreading process with the user-specific spreading code from the reception spreading code generator, and those signals which have undergone the despreading processes are demodulated by data demodulators to extract desired information together with a desired signal corresponding to a wide band service. It is therefore possible to simplify the management of the individual users and individual services and facilitate the system design.
