Throughput Improvement for Cell-Edge Users Using Selective Cooperation
Mahesh C. Patil | Sandeep M. Kate
Abstract: In this paper, we introduce the technique mainly to improve the performance of the mobile phone users who are at the edge of the cell. In cellular radio system a land area to be supplied with radio waves is divided into regular hexagonal shape assigned with multiple frequencies (f1 f6) which have corresponding base stations. In such an environment inter cell interference do exist and also responsible for degradation of performance. Here in this technique, we use co-operative transmission to improve the spectral efficiency. Here downlink capacity of cell edge users is evaluated. Co-operative scheme of base stations is responsible for to improve the spectral efficiency. Throughput and Signal to interference noise ratio (SINR) of cell edge users is co-ordinated by the base stations and transmission is controlled through base stations. Selective co-operation is being introduced here where the selection criteria is based on throughput.
Keywords: Signal to interference noise ratio SINR, Spectral efficiency, Cell edge user
