TY - JOUR A1 - Valenzuela Valdés, Juan Francisco AU - Martínez González, Antonio Manuel AU - Sánchez Hernández, David Agapito T1 - Effect of user presence on receive diversity and MIMO capacity for rayleigh-fading channels Y1 - 2007 SN - 1536-1225 UR - http://hdl.handle.net/10317/834 AB - The effects of the presence of the user on multipleinput– multiple-output (MIMO) performance for wireless communications systems is investigated through measurements in a reverberation chamber. 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.
