具有多通道可重构数字下变频系统
Reconfigurable Digital Down Conversion System with Multiple Channels
摘要
Abstract
In order to achieve multi-mode multi-band signal reception,reconfigurable digital down conversion system based on FPGA with multiple channels is proposed. A single-channel system by system generator is built,which is generated as HDL code.Then the system is achieved on Virtex6 ML605 target board.Intermediate frequency is mixed by DDS,then sum frequency is got. After that signal is divided into two channels,one goes through 50 times CIC and decimation half-band filter to get a lower frequency,the other goes through 5 times down and half-band filter to get another frequency signal. Each module of two channels is designed as profile of dynamic configuration. Configuring different profiles achieves virtual reconfigurable multi-channel digital down-conversion system. Compared resources of each channel with reconfigurable system,reconfigurable system is higher utilization of resources.关键词
