| 摘 要： | 针对LS—DRCMA（解扩重扩最小二乘算法），提出了一种采用FPGA＋DSP结构实现的智能天线系统。根据LS—DRCMA算法对数值特性的要求和Xilinx公司的Virtex－4以及TI公司的TMS320C6416T硬件结构适合进行定点运算的特点，采用双FPGA＋单DSP结构来实现整个算法，并详细阐述了软硬件的实现和优化。实验结果证明，该系统收敛速度快，扩展性能好。

| Abstract: | A method of smart antenna using LS-DRCMA （least squares-ee-spread re-spread constant module algorithm） is introduced based on FPGA ＋DSP. Owing to the numerical characteristics of LS-DRCMA, and taking account of the structure of TMS320C6416T and Virtex-4 which are suitable for the characteristics of fixed- point operation, the system is implemented which is made up of double FPGA ＋DSP. Experiment results indicate that the system has a significantly faster convergence rate and better tracking ability. |
