Abstract:
A code-multiplexing communication apparatus including:a splitting means for splitting incoming serial transmitted data into N (N is integer equal to or greater than 2) number of signal sequences; N number of spread means for performing spreading for each of the N number of signal sequences with use of a spread code; an adder means adding the N number of signal sequences with the spreading processed by the N number of spread means, for outputting a code-multiplexing signal; and a modulating means for modulating the code-multiplexed signal, comprising: a filter having an inverse characteristic to a frequency characteristic of an autocorrelated distortion caused by the spreading wherein the filter is provided on a succeeding stage of the adding means, wherein the filter includes a transversal filter having a plurality of delay elements, a plurality of multipliers, and a plurality of adders.
