Recently, demands for high-speed and wide-band wireless communication system have been increasing significantly. MIMO transmission technologies are taking an important part in these systems and will be paid more attention in the future. However, performance of MIMO transmission highly depends on radio propagation environment and it is necessary to build an accurate MIMO channel model in order to evaluation the performance. Propagation channel parameter estimation is a big part in Ray-based MIMO channel model and its accuracy has a big influence on the model. EM/SAGE is well known as a high resolution parameter estimation algorithm but it still has a drawback of slow convergence and accuracy. This study aims at improving EM algorithm by introducing non-linear conjugate gradient method. |
