Abstract: A multiplexing timing signal generator (1) generates a multiplexing timing signal activated for each interval corresponding to a number of chips delayed in multiplexing between data to be transmitted. Driven by the multiplexing timing being active, each operation unit multiplies identical data to be transmitted by a chip of a spreading code sequence and each chip corresponding to a spread spectrum result is added in an operation unit 3(1) to an offset value and in operation units 3(2)–3(N) to their respective, immediately preceding registers 2(1)–2(N?1) values and output as signals for subsequent registers 2(1)–2(N). Thus a multiplexing process is effected. Data to be transmitted has its spectrum spread by a spreading code sequence C1–CN and a result of multiplexing the same in response to a multiplexing timing signal is output from a register(2(N)) by 1 chip at a time in synchronization with a clock signal.
