This paper describes a wideband CDMA system with TDMA structure so that the system has the advantages of both CDMA and TDMA technology. Also, the proposed system has the optional single-user type adaptive interference canceller (AIC), which works without information about other users and is able to cancel not only the interference in the same cell but also the unexpected signal such as the interference from other cells. Furthermore, this AIC has a RAKE effect. To investigate the system performance, a field test is implemented in an urban area. From the results, it becomes clear that the basic system performance without AIC is good and the AIC is able to cancel the interference and works well in the vehicular environment.
