摘要
论文先对R矩阵采用一种新颖的Cholesky分解方法,再根据定点DSP的特点对其递归公式进行相应的改进,然后与传统的Cholesky分解方法相比较。仿真表明,改进的Cholesky分解方法具有良好的数据精度和可行性。
In this paper, a new method-Cholesky decomposition to R matrix is adopted, and then the recursion expression ameliorated according to the attributes of fixed DSP. Afterwards this new Cholesky decomposition method is compared with the traditional one. Simulation indicates the ameliorated Cholesky decomposition method features high data accuracy and feasibility.
