  • Abstract
    Channel estimation is an important link in the receiver of TD-LTE system, it´s accuracy that directly affects the system performance. Research and analysis of Channel estimation are proposed based on pilot signal. The paper especially discusses taking advantage of LMMSE algorithm based on QR decomposition. At last, an implementation approach is proposed in this paper. The running results verify that the program is feasible and effective.
