摘要：
This paper describes a developed W-CDMA base station testbed with a practical multi-stage interference canceller, which is processed by high-speed digital signal processing cards. The multi-stage canceller features par allel structure with a cancellation control factor, which can make parallel cancelling operation stable. Laboratory experiment demonstrates that the developed interference canceller has high cancelling capability and near-far resistance even when the interference (2 users) power is 9dB higher than the desired user. The development and experiment proves that this multistage canceller is feasible and effective technology for W-CDMA performance enhancement.
