Abstract
A system and method for allocating channelization code and scrambling code in multiple code rates is disclosed. In the present invention, many user signals that have various chip rates in overlaid frequency band can be transmitted with minimum interference between users, by allocating orthogonal spreading code in which the sum of bits for a period that is determined by the ratio of chip rates is canceled respectively, as channelization codes.
