1. the equipment in wireless communication system, it comprises:

  • Processor, its operation is to produce modulation symbol, by being replicated L time by modulation symbol sequence and the modulation being replicated being accorded withNumber sequence is multiplied by L chip of spreading code and to extend described modulation symbol to obtain for code division multiplex with spreading codeL the extension modulation symbol of CDM, and produce based on described L extension modulation symbol and one group of continuous sub-band for transmissionAt least one single-carrier frequency division multiple access SC-FDMA symbol, wherein L is the length of described spreading code;

    AndMemorizer, it is coupled to described processor.
