Three methods for extracting the behavioral modeling coefficients of the memory polynomial model are compared herein. The first one is the ordinary least square regression, which is widely used for adjusting model parameters; the second is the order recursive least squares, which is suitable for exploring the optimal nonlinearity order and memory depth by comparing subsequent errors while increasing...
In this paper, we propose a new fast parallel sparse matrix-vector multiplication (SpMV) algorithm on GPU platforms. The new algorithm, called segSpMV, is based on the compressed sparse row (CSR) format and can be applied to wide computational applications with both structured and unstructured matrices. The SpMV operation has very low computing to communication ratio and is bandwidth-limited. The...
