Adaptive Interference Cancellation Method in Wireless Repeater System

Pilot Interference Cancellation in a WCDMA wireless Repeater

In this paper, we propose a mitigation method to reduce the effect of pilot interference at the wireless repeater. Using an adaptive estimation algorithm, we estimates undesired pilot signals from neighboring base stations and eliminate these interference signals from the received signals. This approach is based on the conventional pilot signal cancellation techniques for a user equipment. This...

NLMS Adaptive Digital Filter with a Variable Step Size for ICS (Interference Cancellation System) RF Repeater

In the NLMS (normalized least mean square) adaptive filters, choosing a suitable step size is crucial as the stability and the steady-state convergence error of the adaptive filter heavily depends on the step size value. In this paper, we propose a new VSS (variable step size) control method for the NLMS adaptive filter applicable to on-frequency RF repeaters that operate under fading feedback ...

Interference Cancellation and Scheduling in Wireless Networks

SIC (Successive Interference Cancellation) is an effective way of multiple packet reception (MPR) to fight with interference in wireless networks. Most of the existing methods for SIC in wireless networks are mainly focusing on link scheduling. For characterizing the impact of SIC, two interference models such as layered protocol model and layered physical model are introduced. Various existing...

Adaptive Blind Interference Cancellation in Cdma Systems

Multiuser CDMA communication systems experience multiple access interference as well as multipath distortions and require some interference cancellation scheme at the receiver. While blind multiuser receivers have received considerable attention, adaptive versions are often limited to the no multipath case. In this paper, the receiver’s output variance is minimized subject to appropriate constr...
