For avoiding severe performance degradation led by the inter-cell interference in OFDMA systems with the frequency factor 1, the distributed coordination algorithm and coordination proportional fairness algorithm based on orthogonal complement space are proposed.

为了防止小区间干扰严重降低频率复用因子为1的OFDMA系统性能，提出基于正交补空间的分布式干扰协调算法和比例公平干扰协调算法。

The CO-OCS algorithm chooses the right regular vector of the user channel as the beamforming vector and the row span as an interference space from the left regular vectors of the interference channels. A suitable user lying in the orthogonal complement space of the interference space is scheduled to be free of suffering inter-cell interference and aggravating the interference in neighboring cells.

分布式干扰协调算法根据用户反馈的信道信息，以用户信道右奇异值向量发送波束成形，以干扰信道左奇异值向量张成干扰空间，按照最大化系统容量准则调度干扰空间的正交补空间中的用户，在躲避小区间干扰的同时不增加对邻小区的干扰。
