Field Test Performance and Analysis of a Base Station to Cancel Wideband CDMA Interference

摘要

This paper reports the field test performance of a base station (BS) equipped with a linear parallel multi-stage interference canceller for uplink of wideband CDMA in a subur- ban area. The field test was performed with one desired mobile station (MS) moving around the BS, and three fixed interfering MSs having a target SIR 11 dB higher than that of the desired MS. The field test clearly demonstrates that using interference cancellation with a proper suppression factor (or weighting fac- tor), can reduce the transmission power of the desired MS by around 6dB.
