Measured results have demonstrated that despite a decrement on the envelope correlation coefficient, a degradation of both diversity gain and MIMO capacity are expected when the user is present. While the validity of the correlation coefficients for predicting MIMO performance is limited in the presence of the user, the effects have also been found to be strongly dependent upon frequency, antenna topology, and user characteristics. %K Teoría de la Señal y las Comunicaciones %K Coeficiente de correlación %K MIMO %K Potencia absorbida %K Sistemas de multiple salida y multiple entrada (MIMO) %~ GOEDOC, SUB GOETTINGEN
