在分析高效宽频带变频系统的基础上提出一种可以把变频部分与多种调制方式灵活结合在一起的方法，并以QAM调制为例，给出具体算法．分析结果表明，该方法降低了对处理速率的要求，提高了处理能力(In order to design an efficient and flexible DDC／DUC system，this paper combined the signal processing of DDC／DUC with QAM system and presented a new method based on the analysis of this efficient broadband DDC／DUC system．QAM modulation was taken for example，and a detailed algorithm of a channel system with 0～30 MHz and 60 channels QAM was presented)

该程序实现二维的FFT变换，可以对图像做FFT变换，运行速度还可以。(procedures to achieve the two-dimensional FFT transform, the image can be done FFT, can also speed.)

说明：  ar burg算法的matlab程序，可供参考(ar burg algorithm matlab program, available for reference)

含代码，WLS计算，加权最小二乘法计算，含代码。(WLS calculation, weighted least squares calculation, containing code.)
