Analysis of non-overlapping domain decomposition algorithms with inexact solves
In this paper we construct and analyze new non-overlapping domain decomposition preconditioners for the solution of second-order elliptic and parabolic boundary value problems. The...

A Frequency-Domain Correlation Matrix Estimation Algorithm for MIMO-OFDM Channel Estimation
— The second-order statistics of a time-domain signal are very often used in blind and semi-blind channel estimation. Considering that the received signal in MIMO-OFDM systems mi...
