摘　　要：介绍了多入多出-正交频分复用(MIMO-OFDM)系统,并分析了其发射机的实现原理。充分利用Altera公司Stratix系列现场可编程门阵列(FPGA)芯片和IP(知识产权)核,提出了一种切实可行的MIMO-OFDM基带系统发射机的FPGA实现方法。重点论述了适合于FPGA实现的对角空时分层编码(D-BLAST)的方法和实现原理以及各个主要模块的工作原理。并给出了其在ModelSim环境下的仿真结果。结果表明,本设计具有设计简单、快速、高效和实时性好等特点。In this paper, multi-input multi-output orthogonal frequency division multiplexing （MIMO-OFDM） system was introduced, and the implementation principle of the transmitter was analyzed. Making full use of Stratix series field programmable gates array （FPGA） chips of Ahera Company and IP （Intellectual Property） core, a feasible implementation method based on FPGA for MIMO-OFDM baseband system transmitter was proposed. This paper selectively analyzed the method and theory of diagonal bell laboratories layered space-time （D-BLAST） adapting for FPGA imPlementation and working principle of each main module. Simulation results with ModelSim were presented. Results showed that this design had a feature of simple, fast, efficient and real-time.
