Simulation and evaluation of MIMO antenna array for wireless communication systems using the paradigm of tensors

Abstract

In this work the use of tensor structures is proposed as a method of MIMO (Multiple-Input Multiple-Output) schemes implementation, with the target to extend the freedom grades that the matrix array provides, this take importance when include more variables of the system for transmit or receive information a major flexibility is achieved, but with a cost of computational complexity. It was verified that the use of tensor structures in the MIMO schemes allows to obtain the same results of the bit error rate and give the possibility of increase the freedom grades in the transmit structure. Finally, results obtained with the tensor scheme, using the theory of singular valué decomposition (SVD) which is achieved a better response were optimized through the use of channels with better characteristics in terms of reduced distortion and higher signal yield scheme, at the expense of a delay in the system response and increased computational complexity.
