在宽带代码分割的 downlink 多重存取(WCDMA ) 或 WCDMA- 高速度 downlink 包存取(HSDPA ) 系统,频率复用因素等于 1,它从邻居房间导致更可能的合作隧道干扰。处于这种状况,有传统的接收装置的用户设备(UE ) 将在房间的边受不了重要表演降级。解决这个问题,就干扰缓解而言的接收装置结构为第三产生的合伙工程(3GPP ) 的长期的进化(LTE ) 被建议了。如此的接收装置使用所有介入的房间的隧道信息执行一个线性最小的均方差(LMMSE ) 均等算法。在这篇文章,一个改进均等算法被介绍,它简单地增加更多的样品动一个均等手术。模拟证明建议算法能在频率获得可观的表演改进选择褪色隧道,与亲戚,很少另外的复杂性介绍了。
In the downlink of wideband code division multiple access (WCDMA) or WCDMA- high speed downlink packet access (HSDPA) system, the frequency reuse factor is equal to 1, which leads to more possible co-channel interference from neighbor cells. In this situation, user equipment(UE) with traditional receiver will suffer from significant performance degradation at the edge of the cell. To solve this problem, a receiver structure considering interference mitigation has been proposed for long term evolution(LTE) of third-generation partnership project (3GPP). Such receiver makes use of all the interfering cells' channel information to perform a linear minimum mean square error (LMMSE) equalization algorithm. In this article, an improved equalization algorithm is presented, which simply adds more samples to perform one equalization operation. Simulations show that the proposed algorithm can obtain a considerable performance improvement in frequency selective fading channel, with relative little additional complexity introduced.
