Abstract

The 3G telecommunication system uses DS-CDMA as air interface. It has been proven many times in the literature that CDMA based multiple access methods are inherently interference resistant, but in some cases the performance of the DS-CDMA is decreasing due to the interference. In this paper, we discuss about nearby TDMA based cellular system and its effects to the performance of the DS-CDMA system. We will discuss about the load and cell capacity issues also in this paper. The basic receivers are rake and parallel interference canceller (PIC) receiver, i.e. no special attention is paid to suppress the TDMA originated interference. We will show the effects of the TDMA interference to both rake and PIC receiver performance. We do not include the other cell interference in this treatment.
