[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 .
