分布式天线系统信道选择策略

分布式天线系统的信道分配问题是整个系统发挥优势的关键之一,考虑选择四根天线的情况,采用动态信道分配方案,对于随机、最大SIR、最小SIR和最大SIR最小等方案进行仿真分析,最小SIR由于使得信道分配达到最大紧致,阻塞率最低,充分利用频谱资源.

Channel Selection Strategies for Distributed Wireless Communication System

Channel assignment problems on distributed wireless cotmmunication system (DWCS) are part of the keys if the predominance of the system can be achieved. By dynamic channel assignment schemes, simultaneously selecting four antennas to serve for the same user, we will simulate and analyze the random SIR strategy, MAX SIR strategy, MIN SIR strategy and MAX MIN SIR strategy. Among the channel selection strategies, the blocking rate of MIN SIR strategy is the lowest one, be- cause in natural MIN SIR strategy is a channel compact pattern and the co--channel visual cells can be packed, so that the chan- nel resource can be reused efficiently.
