Preliminary study on CDD system using smart antenna

Abstract

This paper deals with the preliminary study on code division duplexing (CDD) system in wireless network using adaptive smart antenna. In particular, we proposed a new technique to mitigate the co-channel interference problem through multiple beams with adaptive power control. Base on this study, some other impairments such as multipath fading and delay spread in wireless environment could be overcame easily by introducing smart code with some time shift in CDD system.
