Abstract
An evaluation of a direct sequence spread spectrum wireless LAN based on interference cancellation techniques is presented, using a simulation toolset based on a hierarchical block diagram approach. Good orthogonality between spreading codes with near-perfect average power control is essential for adequate spectrum efficiency in conventional CDMA applications but good average power control is often difficult to maintain. Interference Cancellation Code Division Multiple Access (IC-CDMA) is a method proposed for third generation mobile systems which considerably improves the user capacity of a spread spectrum system. IC-CDMA does not require equal received powers thereby eliminating the need for complex power control algorithms. The results obtained illustrate that IC-CDMA is generally more suitable for a cellular application than conventional CDMA.
