摘要
分析了传统模拟解调方法的缺陷,对数字乘积检波(DPD)算法加以改进,并应用FPGA+DSP线性流水结构,提高了算法的计算效率和器件的利用率。最后,对硬件实现的核心部分作了详尽的阐述。
This paper analyses the disadvantage of the traditiona l means of the analog demodulation, ameliorates the arithmetic of Digital Product Detector (DPD) and uses the linear pipeline architecture of FPGA plus DSP to inc rease the computing efficiency of the arithmetic and the efficiency of the appar atus. At the end of the paper, we expatiate the kernel part of the hardware.
