Analysis of interference cancellation for a multicellular CDMA environment

This paper considers the performance of adaptive interference cancellation applied to a CDMA microcellular environment, by employing a circular geometry and a closed form expression for the bit error rate of a CDMA system with interference cancellation to analyze the effect of out-of-cell interference. Results indicate that out-of-cell interference will severely limit the benefits of interference cancellation in a multicellular system. Attempts to cancel all out-of-cell interference will further degrade the performance. However, selective interference cancellation in which only the strongest out-of-cell interferers are cancelled may result in significant performance enhancement
