Wenbo Wang · Radio Engineering of China · 2006
This paper presents an interference cancellation scheme which is suitable for TD-SCDMA system when the timeslot allocation is different.Based on the priori information of timeslot allocation between the basestations and the estimation of the power of angle spectrum,null steering technique is utilized to cancel interferece of intra-basestation.Simulation results have shown that the performance of the proposed scheme is greatly improved compared with the parallel interference cancellation algorithm of multi-user detection,and it increases the spectrum efficiency.
