Performance Analysis of a Fixed-point Successive Interference Canceller for WCDMA
Paper in proceedings, 2004

In this paper we study the problem of implementing a successive interference canceller (SIC) for a WCDMA system in fixed-point electronics. Typically, fixed-point implementation is based on an iterative design of simulations and experience, resulting in a time-consuming and inefficient process. From the experience of a conventional design with simulations, we make a model of the fixed-point SIC. The advantage with this model is that it can be analyzed and hence be used to predict the performance of a fixed-point implementation with given precision. Simulations indicate that the analysis agrees well for moderate system load and especially for the high precision case. which is the case of most interest. Hence, it much simplifies the design procedure of fixed-point implementation of SIC.
