Uplink Carrier-to-Interference Improvement in a Cellular Telecommunication System When a Six-Beam Switched Parasitic Array Is Implemented
By
Progress In Electromagnetics Research B, Vol. 5, 303-321, 2008
Abstract
Mobile broadband communication is experiencing rapid growth in the following sections: technology,range of services and marketing target groups. This growth has driven research and development activities towards advanced high-data-rate wireless systems, with improved network performance. A typical example of technology thrust in wireless communications is the use of adaptive antennas at the transceivers, in association with advanced array signal processing. Although the mass deployment of adaptive array systems has not achieved the desired levels yet,there are many examples of improved cell coverage, link quality and system capacity at several networks. The performance of a six-beam switched parasitic array, in terms of carrier-to-interference ratio (CIR) measurement at the uplink direction, is presented in this paper. The switched parasitic array is designed with the aid of the method of genetic algorithms and the simulation results are compared with respect to those obtained when an omni directional antenna is used instead. The calculated CIR improvement reveals the superiority of the adaptive system compared to the conventional one.
