A code-multiplexing communication apparatus includes a splitting unit for splitting incoming serial transmitted data into N (N is integer equal to or greater than 2) number of signal trains; N number of spread unit for performing spreading for each of the N number of signal sequences with use of a spread code; an adding unit adding the N number of signal sequences with the spreading processed by the N number of spread unit, for outputting a code-multiplexed signal; and a modulating unit for modulating the code-multiplexed signal, comprising, filter unit having an inverse characteristic to a frequency characteristic of an autocorrelated distortion caused by the spreading, removing a transmission path distortion.
