EFFECTS ON MULTI-USER DETECTION IN DS-CDMA SYSTEMS IMMERSED IN NON-GAUSSIAN ENVIRONMENTS

摘要

In this paper, we evaluated the performance of different multi-user detectors for DS-CDMA systems in non-gaussian channels. These kinds of channels appear mainly, due to the impulsive characteristics of the man-made electromagnetic environment where these systems work. Results obtained by simulation show that, in general, the performance of all multi-user detectors decrease when the noise channel has impulsive characteristics.
