Abstract (in Japanese) (See Japanese page) 
(in English) High data rate and high spectral efficiency more than LTE can be obtained by different orthogonal codes DS/CDMA communication systems. This paper evaluates bit error rate (BER) performance by interference cancellation employing other user signal regeneration when the interference is occurred by adopting indoor radio wave intensity of a wireless LAN in a laboratory and a corridor measured by spectrum-analyzer, and interference quantity is estimated by computer simulations. Then, giving interference quantity to the system, moving the positions of own user and other user, we compare results before interference cancellations with that after them in the system, and show these effects.
