基于线性约束LSCMA在TS101上的实现

本文探讨了ADSP TigerSHARC101S 的在基于线性约束最小二乘恒模算法(LSCMA)中的应用。首先介绍了最小二乘恒模算法基本原理和权值迭代公式， 并对其进行线性约束然后介绍了ADSPTigerSHARC101S 芯片的基本结构特征和它强大的功能并简单描述了其相应开发软件Visual DSP++3.0 的功能及使用方法。给出了最小二乘恒模算法实现波束合成的具体流程图，在经过Matlab 软件成功进行仿真模拟之后用Visual DSP++3.0 设计了DSP 程序，用C 语言嵌套部分汇编语言的形式实现了用ADSPTigerSHARC101S 进行迭代求权向量的过程。

[Abstract]：This article describes the application of ADSP TigerSHARC101S in the Least Squar Constant Modulus Algorithm based on Linear Constrains . First it makes a general introduce for the basic theory of CMA, of which flow chart is presented detailed later , the formula of weight’s iterative and describes the basic feature of the chip’s configuration as well as its powerful function. After a seccessful computer simulation with the software-MALAB , design a program by Visual DSP++3.0 to realize the course of weight vectots’ iterating with C
language partially embeded by assemble language .
