通用射频平台中数字前端模块的FPGA实现
Realization on the Digital Front-end of RF Platform by FPGA
通用射频平台的数字前端模块是射频收发模块中的一个部分，它是收发机的射频前端和以DSP为核心的基带信号处理的桥梁，主要包括对中频或基带信号进行高速数字信号处理。本文提出了基于FPGA的整套数字前端方案，包括实现数字上下变频，可变速率的多采样率数字信号处理，射频模拟滤波器的补偿，IQ两路信号的幅度和基准点不平衡问题的补偿，功率补偿。对于可变速率的多采样率数字信号处理模块与模拟补偿滤波器模块，都给出了相应的仿真波形。
igital front-end in RF platform is an important part of tranceiver, which is to bridge the RF analog front-end and the baseband signal processor. It also implements the high speed digital IF or baseband signal processing. In this paper, the whole design in FPGA is presented ,including DDC/DUC module variale rate data processing module,analog filter compensation module,compensation of IQ DCoffset and amplitude module, power compensation module.Especially to variale rate data processing and analog filter compensation module,this paper provides some simulation results.
