摘要
针对软件无线电接收机中数字下变频的特点,提出了一种合理的基于FPGA实现宽带数字下变频的方案,并利用Matlab中的Dspbuilder提供的IP核得到了总体的仿真结果。该接收系统用于WCDMA移动通信网络的基站体系中,能很好地实现手机信号覆盖和传输。
Based on the discussion of the structure of digital down-conversion（DDC） in software radio receiver,The paper put forward a reasonable solution program of wide band DDC in FPGA,and provides the whole simulation result by Dspbuilder IP core in Matlab.The receiving system used for base station system in WCDMA mobile communication network,would realize the cell phone signal coverage and transmission very well.
