最近，我们提出了一种基于干扰感知的信道分离动态信道分配算法(IACS-DCA)。在IACS-DCA中，每个基站(BS)测量每个可用信道上的瞬时同频干扰(CCI)功率，使用过去的CCI测量结果计算移动平均CCI功率，并选择具有最低移动平均CCI功率的信道。通过这种方式，可以形成CCI最小化的信道重用模式。本文引入了信道重用模式的自相关函数、信道重用的公平性和最小同信道BS距离来定量检验IACS-DCA所形成的信道重用模式。结果表明，IACSDCA能够以分布式方式形成CCI最小化的信道重用模式，并且与其他信道分配方案相比，它可以提高信干比(SIR)。
SUMMARY Recently, we proposed an interference-aware channel segregation based dynamic channel assignment (IACS-DCA). In IACS-DCA, each base station (BS) measures the instantaneous co-channel interference (CCI) power on each available channel, computes the moving average CCI power using past CCI measurement results, and selects the channel having the lowest moving average CCI power. In this way, the CCI-minimized channel reuse pattern can be formed. In this paper, we introduce the autocorrelation function of channel reuse pattern, the fairness of channel reuse, and the minimum co-channel BS distance to quantitatively examine the channel reuse pattern formed by the IACS-DCA. It is shown that the IACSDCA can form a CCI-minimized channel reuse pattern in a distributed manner and that it improves the signal-to-interference ratio (SIR) compared to the other channel assignment schemes.
