摘　　要：文中创建了基于OPNET和MATLAB接口机制的无线通信联合仿真平台,以充分利用MATLAB的链路层仿真优势,并把物理层MIMO技术有效融入到OPNET仿真平台。在该平台上仿真了基于预编码码本的随机调度(Opportunistic scheduling)SDMA系统;并对其进行了改进,引入了比例公平算法以保证实际系统中用户调度的公平性。This paper creates a simulation platform of MIMO wireless communication system based on the interface mechanism between OPNET and MATLAB,facilitates the superiority of link layer simulation of MATLAB,and affiliates the physical layer of MIMO technology with OPNET simulation platform. It simulates the opportunistic scheduling SDMA system based on the precoding codebook with the above platform; and it optimizes the opportunistic scheduling SDMA system, importing the algorithm of proportional fairness to ensure the fairness of user scheduling in practical system.

关 键 词：预编码 联合仿真 随机调度 比例公平
