ABSTRACT:
A spread code allocation method in a CDMA cellular having a first code set including a plurality of first codes and a second code set including one or a plurality of second codes, allocating the second code to the first code set and multiplying the plurality of first codes by the allocated second code to generate a plurality of combined codes, assigning a priority to the combined code for each transmission signal to be transmitted from a base station to a mobile station, allocating the combined code to the transmission signal based on the priority, and diffusing the transmission signal by the allocated combined code to transmit the diffused transmission signal to the mobile station.
