Abstract

This paper reports the field test performance of a base station (BS) equipped with a linear parallel multi-stage interference canceller for uplink ofwideband CDMA in a suburban area. The field test was performed with one desired mobile station (MS) moving around the BS, and three fixed interferingMSs 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 factor), can reduce the transmission power of the desired MS by around 6 dB. This performance was also compared with calculated data and the interference canceller was verified to functionas theoretically expected. The receive power capture ratio was estimated at around 96%. This paper therefore establishes that interference cancellation performance of CDMA systems in the field can be found by estimating the receive power capture ratio and the theoretical results of interference cancellation.
