Performance Analysis of Inter-cell interference Mitigation with Beam-forming for E-UTRA System
首发时间:2006-10-18
Abstract:For Evolved-UTRA system based on Orthogonal Frequency Division Multiplexing (OFDM), with orthogonality within the cell, the main interference will be inter-cell interference. It is important to consider what techniques to be used in E-UTRA to handle inter-cell interference. The common theme of inter-cell interference coordination/avoidance is to apply restrictions to the resource management in a coordinated way between cells, whatever static, semi-static or dynamic coordinated way. The restrictions of transmit power or time/frequency resource will provide the possibility for improvement in signal-to-interference ratio. In this paper, the combination of beam-forming with inter-cell interference coordination/avoidance approach will be analyzed. And some simulation results will be given to further analyze the performance of inter-cell interference mitigation with beam-forming and the combinations. Beam-forming can be easily combined with other inter-cell interference mitigation approaches for more efficient inter-cell interference suppression.

E-UTRA系统中结合波束赋形的小区间干扰抑制技术的性能研究
摘要:基于正交频分复用(OFDM)技术的E-UTRA系统,由于小区内用户间是正交的,小区间干扰将成为系统内主要的干扰。因此,采用何种技术来处理小区间干扰是一个至关重要的问题。小区间干扰协调/避免的方法通常是在小区之间以一种协调的方式,静态的、半静态的,或是动态的协调方式对资源管理进行限制。这种对传输功率或时频资源的限制为提高信干比提供了可能。本文分析研究了一种小区间干扰协调/避免结合波束赋形来抑制小区间干扰的方法,并给出了波束赋形及两者相结合的方法的仿真结果。仿真表明波束赋形可以和其他小区间干扰抑制的方法相结合来进一步有效地抑制小区间干扰。
