Abstract: PURPOSE: A transmit-receive method and apparatus using spreading modulation in a band spreading communication system is provided to improve the deterioration of a PAR(Peak-to-Average Ratio) characteristic, due to transition to the origin, by making the transition-to-origin probability of a descrambling signal(xT(n) + jyT(n)) into '0' in all visual angles but a visual angle n=0 (mod min{SFPiCH, SFDCCH, SFSCH2, SFSCH1, SFFCH}). CONSTITUTION: Taking the transfer data of SCH#1 and SCH#2 as the first input and OVSF(Orthogonal Variable Spreading Factor) codes(HSCH1(n),HSCH2(n)) as the second input, the first complex multiplier(142) executes a primary orthogonal complex spreading. The output of the first complex multiplier(142) and the PiCH, DCCH and FCH spread by HPiCH(n), HDCCH(n) and HFCH(n) are inputted to adders(130,132). A spreading modulator(141) generates and outputs IT(n) and QT(n), taking the outputs(xT(n),yT(n)) of the adders(130,132) as the first input and primary scrambling codes(C1(n),C1(n)) as the second input. The spreading modulator(141) is composed of a scrambling code generator(520) and the first complex multiplier(142). The scrambling code generator(520), receiving the primary scrambling codes(C1(n),C1(n)), generates secondary scrambling codes(Cscramble,I(n),Cscramble,Q(n)).
