摘要:
针对单天线双层毫微微小区系统下行中断性能进行研究,分别给出了宏小区和毫微微小区的下行中断性能的数学表达式,特别针对当层间或层内干扰信号的路径损耗指数α=4.0时,由于来自毫微微小区的聚合层间或层内干扰服从L(e)vy平稳分布,通过数学分析推导出了每层下行平均中断概率的闭式表达式.利用数值仿真揭示了不同参数对中断性能的影响,并证明了理论推导的正确性.
Abstract:
The downlink outage performance in single two-tier networks is studied.The mathematic expressions of outage probability in Marco cell and femto cell is derived.Especially,when inner-layer or inter-layer interfering signal path loss exponent α=4.0,the interference aggregation from inner-layer or inter-layer obey Lévy stable distribution.The closed expressions of downlink average outage probability in each layer by mathematic analyzes is derived.Using numerical simulations,it reveal the performance of different parameters on the impact of outage probability,and proved the theoretical analysis.
