ABSTRACT:
A next alternative storing memory that stores a next alternative code is included in a CDMA cellular telephone, so that when demodulated data cannot be obtained, in the case that a code as a next alternative has been stored in the next alternative storing memory, a partial searching process is performed with the code so as to demodulate data. When data can be demodulated, a searching process is performed with the code.
