Description: 随着数模转换器硬件的快速发展和DSP处理能力及处理速度的逐步提高，软件无线电技术在商用和军用无线电通信领域也越来越显示出其强大的吸引力。本文研究的高速中频采样和数字下变频技术是目前蓬勃发展的软件无线电领域的两项关键技术。-As advances in technology provide increasingly faster and less expensive digital hardware, more of the traditionally analog functions of a radio receiver will be replaced with software or digital hardware. The software radio has show its fascinating functions in both commercial and military wireless communication. The high speed and high resolution analog-to-digital converter and digital down-converter which are researched in this thesis are two of the key technologies in the field of software radio that is vigorously developing recently.

Description: 我对一个输入调制信号：采样率FS=1200K，中心频率F0=300K，带宽300K。输入信号为一个[样点数,2]的矩阵,即I,Q两路.
进行频谱搬移，分为I，Q分量两路进行矢量乘法，NCO的设置为FC=300K，t=样点数乘以1/FS，
乘完以后我的频谱上显示竟然信号带宽增加了300K，但是中心频率没有改变，请问各位朋友是哪儿出了问题？谢谢您的阅读和意见-Digital Down Converter for matlab realized, certain design specifications that can be used to know VHDL Programming Platform: |

Description: 文中应用软件无线电思想对数字下变频器中的几个关键技术进行了研究,对下变频各个模块所涉及到的CIC、HB、FIR等关键算法进行了讨论、提炼与总结,应用matlab软件设计了下变频器中的CIC、HB、FIR滤波器等核心模块,并将各模块融为一体从软件实现的角度完成了对系统的搭建和功能仿真.仿真结果表明,系统实现了对中频信号的下变频处理且无失真现象,大大减少了软件无线电系统数宁信号处理的运算量和数据的存储量,极大地提高了系统的实时性.-The paper application software radio digital down converter in the thinking of several key technologies have been studied for the next conversion involved in each module to the CIC, HB, FIR and other key algorithms were discussed, refined and summarized the application of matlab software design downconverter in the CIC, HB, FIR filters and other core modules, and integration of various modules from the software point of complete structures and functions of the system simulation. The simulation results show that the system achieved the right under the IF signal Frequency processing and without distortion, thus greatly reducing the number of software-defined radio system, rather the amount of signal processing operations and data storage capacity, greatly improve the system in real time.
