| Summary: | 碩士 === 淡江大學 === 電機工程學系碩士班 === 98 === LTE-A technique will play an important roll in the next generation wireless communication system due to it has the advantages of high transmission rate and wide communication bandwidth especially it has high quality throughput when the uses is moving in high velocity. The system performance and parameters characteristics resulting from utilizing LTE-A technique will be provided to the system designers as the references to the development of future IMT-Advanced wireless communication system. When the system bandwidth becomes wider the system utilization performance will be varied widely and becomes inefficiency because the number of users served in the system coverage areas will be varied and the signal transmission environments are changed. It needs to adopt coordination technique among base stations so as to effectively utilize the system resources and to improve the signal purity in its transmission. It has many advantages when considering coordination among base stations such as the reduction of system interference, the improvement of diversity effect and the increase of system gain at the receiver terminal etc. However it has the requirement of increasing system bandwidth when the coordination among base stations is considered.
In this study when the coordination among base stations are implemented the following system characteristics such as the system capacity, the required system bandwidth, the
effect on the users and the performance difference when FDD or TDD technique is implemented etc. will be investigated. Specifically it will also consider the system performance when Femto cells or Repeaters are included in the system. When the data characterizing the system performance are generated and studied they can be provided as references in the base stations installations and they can also be provided as the procedures of how and when to coordinating among various base stations. With Femto cells and Repeaters are included in the system they can be used to simulate the indoor transmission environments and to provide better services to users.
