摘要
大规模集成电路的发展使得数字中频采样收发机成为现实。本文使用宽带中频数字化方案,利用FPGA中的IP核把经过AD转换后的中频信号通过数字下变频处理为基带信号,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。
The development of large scale integrated circuits made implementation of digital IF transceivers. The paper uses the IF digital programs, taking advantage of the FPGA IP core technology, IF signal converted by the AD processing convert baseband signals by digital down converter, 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.
