Performance Analysis in Using Repeaters with Coordination among Base Stations for LTE-A Systems

LTE-A technique will play an important role in the next generation wireless communications due to it has the advantages of high transmission rate and wide communication bandwidth especially it also provides high quality throughput when the user is moving in high velocity. The system performance and parameters characteristics resulting from utilizing LTE-A technique will be provided to the system designers valuable references in their development of future IMT-Advanced wireless communication systems. When the system bandwidth becomes wider the system utilization performance will be varied widely and may become inefficiency when the number of users served in the system coverage areas varies and the communication environments change. It could adopt the coordination technique among base stations to effectively utilize the system resources and to reduce the possible interferences among signals in their transmissions. In this paper it considers of how to utilize repeaters in the base station coverage areas to optimize the spectral efficiency of the base station in its backbone transmission. It utilizes repeaters to improve the indoor signal transmission quality when the users in the indoor environment could not receive the signal transmitted from the outdoor base stations.
