new blind estimation of MIMO channels using HGA was proposed for the frequency selective channel. By exploiting the output statistics, an objective function that coming from blind estimation of MIMO channels based on the subspace could be obtained. Then the fitness function based on the objective function is proposed for optimization by a hybrid genetic(More)
This article studies the classical MDS and dwMDS location algorithm.On this basis, steepest descent algorithm is introduced to replace SMACOF algorithm as optimization objective function. The results show that the steepest descent method as the optimization objective function is simple and easy to implement. Compared with the dwMDS method based on SMACOF(More)
