Abstract :
In this paper, we will study the performance of a model when multiple transmitting antennas are used. The study has demonstrated that the efficiency of the model is independent of the number of transmitting antennas. This is because we have a compressed storage of matrices, and hence the fields can be solved directly by forward and backward substitutions instead of solving the matrix equations repeatedly. Numerical simulations validate the conclusion.
