摘要
针对自适应MIMO-OFDM无线基带传输系统,提出了一种并行复用的基4-FFT/IFFT算法的FPGA实现方法,并对其中的自适应数字调制、STBC编码和FFT/IFFT模块进行了FPGA实现研究和仿真。仿真结果表明,该方法实现了模块的功能,且性能良好,具有一定的应用价值。
For adaptive MIMO-OFDM wireless baseband transmission system, this paper proposed a parallel multiplexing FPGA re-alization method of radix 4 FFT/IFFT algorithm, and made the research and simulation of FPGA implementation for adaptive digital modulation, STBC coding and FFT/IFFT module. The simulation results show that the design realized the function of the modules,and good performance, has certain application value.
