摘要
在3GPP LTE的上行传输中引入了一种虚拟MIMO(V-MIMO)技术。用户配对是V-MIMO技术中一个重要而独特的环节,设计配对算法必须考虑用户吞吐量和公平性。在分析传统的用户配对算法的基础上,提出了一个新的基于SINR(Signal to interfer-ence plus noise ratio)的比例公平(SNIR-PF)配对算法,此算法同时兼顾公平性和高效性并相对降低系统复杂性。同时该文最后通过显示仿真数据来说明这种算法对传统算法的优越性。
In 3rd generation(3G) long term evolution(LTE) uplink transmit there is a virtual multiple-input multiple-output (V-MIMO) technology.User pairing method,which must take user throughput and fairness into consideration,is vital to V-MIMO.In this article,based on the analysis of traditional user pairing algorithms,proposed a new SINR-based proportional fairness user pairing algorithm.The proposed algorithm maintain good balance of performance of throughput and fairness,meanwhile reduce the complexity of device.The simulation results are shown in the end to illustrate the advantage of the proposed algorithm to the traditional ones.
