Abstract: | |
The demand of high data rates is increasing day by day. The user needs to access all the multimedia applications on its mobile phone anytime, anywhere. For this purpose LTE was launched. As LTE provides high data rates, better efficiency to the network, but at the same time LTE-A is affected by interference in downlink, especially at the cell edge. The degradation of connectivity occurs due to inter-cell interference, which occurs when user is receiving the signals from two neighboring base station at same frequency, so in this case the mobile phone can maximize the received signal strength by adding up these two signals coming from two base stations, here problem arises for the user for the selection of base station, so coordination is applied between the cells to reduce the interference between the cells. This paper focuses on coordination between the base stations. DCS (dynamic cell selection selection) is used for coordination among the base stations, which will compare the CSI (channel state information) of base stations. The interference directly affects the parameters such as noise interference, receiving diversity and system receiving gain. In this thesis, SINR of the system is analyzed when coordination is applied between the cells. Initially the SINR is compared without coordination and then SINR is compared with coordination and then the results of both scenarios are compared. |
