Abstract
Interference reduces the signal quality of any cellular network system and is a major problem in Radio Access Network that need to be addressed because its causes degradation of the signal quality thereby reducing the quality of service of the particular network service provider. Hence, interference must be controlled and managed in other to improve the quality of signal in the cellular network system. This research presents a method of interference reduction by canceling interference by regenerated signals from a cellular network by analyzing the network data from the network statistics using the Microsoft Excel tool. This technique regenerates demodulated uplink data signals for High Speed Uplink Packet Access capable User Equipment and cancels interference by the regenerated signals. This technique will reduce the Multiple Access Interference, improves demodulation performance and increase the uplink system capacity in Wideband Code Division Multiple Access (WCDMA) of the cellular network system.
Keywords: Interference, cellular network, uplink, signal, demodulation
