| 摘 要： | 为了抑制软频率复用LTE小区间干扰,基于正交补空间提出了正交调度的小区间干扰分布式协调算法.对同道用户的信道奇异值分解,使用右奇异值向量作为发送波束成形向量,使信噪比最大,以左奇异值向量为空间签名,同道干扰用户空间签名张成干扰空间,调度空间签名在干扰空间的正交补空间的用户消除小区间干扰.该算法是分布式的,不需要基站之间交换信息,仿真表明,该算法能完全协调小区间干扰.

| Abstract: | In order to suppress the inter-cell interference between LTE cells adopt soft frequency reused technique,a distributed coordination algorithm based on orthogonal complement is proposed.The right singular vectors of the channels are selected as the beam-forming vector to maximum the SNR,and the left singular vectors act as the signs.The algorithm schedules the users whose signs are in the orthogonal complement space.Through simulation and analysis,it is proved that the proposed algorithm is efficient in suppressing the inter-cell Interference. |
