【Abstract】 This paper discusses the application of ADSPTigerSHARC101S in the linearly constrained least squares constant modulus algorithm (LSCMA). Firstly, the basic principle and weight iteration formula of the least squares constant modulus algorithm are introduced, and linear constraints are imposed on it. Then, the basic structural characteristics and powerful functions of the ADSPTigerSHARC101S chip are introduced, and the functions and usage of its corresponding development software VisualDSP++3.0 are briefly described. The specific flow chart of the least squares constant modulus algorithm to realize beam synthesis is given. After successful simulation with Matlab software, the DSP program is designed with VisualDSP++3.0, and the process of iteratively calculating the weight vector using ADSPTigerSHARC101S is realized in the form of C language nested in part of assembly language.
