Plots of cumulative probability distribution versus singular value of channel matrix in a 2 × 2 MIMO system for different maximum and minimum singular values in a 2 × 2 MIMO system, on the conditions that the normalized distances of the two dipoles are 0.1λ, 0.2λ and 0.5λ at both ends respectively and the last two conditions correspond to the i.i.d. channels without coupling at both ends.
