【摘要】 讨论宏小区网络中引入微微小区后,由于微微小区与周围相隔一定距离的小区共用信道,会引起共用信道干扰问题。而干扰是增加系统容量的一个重要瓶颈,且常常引起掉话。本文就微微小区内的信号干扰比SIR(Signal＿to＿interferenceration)进行分析,给出了其分析模型和方法。文章中所讨论的信道,是具有对数标准衰落的反向功率控制路径损失规律的信道。更多还原

【Abstract】 The paper will discuss co-channel intereference because microcells share the same channel set with the surrounding macrocell spacing a length of distance,when microcell is introduced into macrocellular.The interference is bottle-neck increasing channel capacity.The channel in this paper is composed of an inverse power-control path loss law with log-normal fading.The SIR is investigated.更多还原
