Summary :

Interference Cancellation (IC) receivers can be used in CDMA cellular systems to improve the capacity. The IC receivers can be divided into two main categories, Single-User Detectors (SUD) and Multi-User Detectors (MUD). They have different characteristics in terms of intra-cell and inter-cell interference cancellation ratios. In this paper we first introduce the Normalized Griffiths' algorithm, a SUD receiver, and compare its basic performance with the well-known Serial IC. Next we examine the multi-cell performance of SUD and MUD receivers by using multi-cell link-level simulations. The results show that even though MUD receiver has clearly better single-cell performance, the SUD receiver will gain in performance in the multi-cell cases. In the three-sector multi-cell case, their performance even becomes very similar. These results are obtained using ideal conditions to be able to study the receivers' basic properties related to intra-cell and inter-cell interference.
