Adaptive interference cancellation system for a WCDMA repeater

This paper examines the problem of coupling in on-channel repeaters for a WCDMA wireless system. Unwanted feedback between the donor and coverage antennas of a repeater are created by radio echoes from local scatterers; as well as direct path antenna isolation limitations. These radio echoes create...

Summary:This paper examines the problem of coupling in on-channel repeaters for a WCDMA wireless system. Unwanted feedback between the donor and coverage antennas of a repeater are created by radio echoes from local scatterers; as well as direct path antenna isolation limitations. These radio echoes create interference not only in the incoming signal from the base station, but also cause instability in the repeater. This paper extends the use of an adaptive interference cancellation system (ICS) presented in to WCDMA signaling scheme. Various new characteristic features of the algorithm are illustrated using the MATLAB simulation results.
