| Abstract: | Aiming at the current situation that power spectrum estimation is computed on CPU via Matlab or other program, a new method in which CUDA is used to accomplish computing power spectrum estima- tion is proposed. Based on theory of classic power spectrum estimation, power spectrum estimation is a- chieved on GPU, and data is outputted via C API provided by Matlab, and also program flows are provid- ed. At last, comparing sheet shows that better performance between CPU and CUDA parallel computing is given. |
