Wireless communication apparatus, wireless communication system and despreading demodulation method used therefor

摘要

The present invention relates to a radio communication apparatus and a radio communication system using a direct spread CDMA communication system, and more particularly, to a radio communication apparatus and a radio communication system using a direct spread CDMA communication system, in which a despreading process of a common signal portion in a received signal is performed by a synthesizing spreading code And the quality of the received signal is greatly improved.;The solving means includes a receiving section (2) capable of receiving a plurality of types of signals subjected to spreading processing with different spreading code information by the CDMA method to the other radio communication apparatus (1A) facing each other via the antenna section (6B) (3) for performing a despreading process using a synthesizing spreading code obtained by synthesizing a plurality of spreading codes with respect to a common signal portion in a plurality of types of signals received by the receiving section (2).
