The interference reduction capability of antenna arrays, base station assignment and the power control algorithms have been considered separately as means to increase the capacity in wireless communication networks. In this paper, we propose base station assignment method based on minimizing the transmitter power (BSA-MTP) technique in a direct sequence-code division multiple access (DS-CDMA) receiver...
It is well known that the implementation of multiple-input multiple-output (MIMO) systems in a cellular environment is hampered by the effects of inter-cell interference. In this paper we look at controlling the base station power to increase overall system capacity. We define the optimization problem and show that the sub-optimal solution, where each base station either transmits at maximum power...
In this paper, a lead compensator is proposed for compensating round-trip delay of direct-sequence code-division multiple-access (DS-CDMA) cellular mobile radio systems. Furthermore, in addition to the delay compensation, a disturbance rejection filter is designed to minimize the effect of uncertain noise and interference to track a desired signal to interference and noise ratio (SINR). The two-step...
In OFDMA cellular system, the inter-cell interference is the dominating interference of the system, which greatly degrades the system performance, especially for the user at cell edge. The power control in uplink is an effective method to control the inter-cell interference. In this paper, we propose a modified uplink power control scheme utilizing the path loss difference between the serving cell...
