Abstract
This paper devotes to the channel estimation of a rapidly time varying environment for TD-HSPA+ technology. Based on the QR factorization of the midamble matrix, a modified channel estimator is proposed. To validate the method, several simulated cases with existing B. Steiner, Least squares (LS) and Minimum mean square error (MMSE) methods are considered. The simulation results demonstrate that the modified factorization method is more efficient, numerically stable and take less runtime than the conventional methods.
