Abstract
AbstractDue to congestion in wireless frequency use, it is difficult to assign an independent frequency bandwidth to broadband wireless communication systems based on the DS‐CDMA (Direct Sequence Code Division Multiple Access) system. Therefore, operation of the DS‐CDMA system on the existing narrowband wireless system is contemplated. However, the interference of the transmitted power of the existing narrowband wireless system on the DS‐CDMA system has not been studied. There is a possibility that significant narrowband interference on the DS‐CDMA system may occur. In this paper, a narrowband interference rejection system in DS‐CDMA is proposed. By making use of prior information on the carrier frequency of the narrowband interference, a narrowband interference rejection process with little computational overhead is realized. © 2003 Wiley Periodicals, Inc.
