Patent ID: 7957361

Claim:
A transmitter of multicarrier signal for a mobile communication system, comprising: a data channel generator configured to multiply a plurality of transmission data sequences by a plurality of short codes; a long code multiplier configured to multiply the plurality of transmission data sequences multiplied by the plurality of the short codes by a common long code; a synchronization signal generator configured to multiply a transmission data sequence for synchronization signal only by a spreading code for synchronization signal; and a transmitter configured to transmit, using a plurality of subcarriers, the transmission data sequences doubly multiplied by the short code and the long code, and configured to transmit the synchronization signal multiplied only by the spreading code for synchronization signal, wherein the synchronization signal generator multiplies the synchronization signal by the spreading code for synchronization signal at plural timings in each iteration period of the long code, and the transmitter transmits the synchronization signal multiplied only by the spreading code for synchronization signal at plural timings in each iteration period of the long code.
