An Adaptive Cooperative Transmission Scheme According to the User Location

Abstract

In this paper, an adaptive cooperative transmission scheme according to the user location is proposed. The proposed cooperative scheme considers the destination user location and applies cooperative scheme properly. If the destination user is located in the cell boundary, the quality of communication is degraded in the broadcasting system. In the conventional scheme, broadcasting base station and cellular base station are used to obtain high performance. However, the quality of communication is not well guaranteed and the transmission distance is increased since the destination user is far from each base station. Therefore, the adaptive transmission scheme for the user location is proposed. In the simulation results, the proposed scheme can obtain more improved performance than the conventional scheme.
