| Sumario: | <p id="p1">In practical 4G/5G MIMO systems, it is difficult to have independent fading among sub channels between different antenna pairs. There will be sub channel correlation between the transmit and receive antenna pairs. Spatial Antenna Correlation (SAC) is an important constraint in the performance of MIMO system capacity. It is observed that, if there is correlation then it effects the random distribution of eigenvalues and more correlation means it is probable that a few eigenvalues are large and rest are small. Therefore, correlation effects the loss in capacity and is bound by its eigenvalue distribution. In this chapter, the different SAC channel effects on Ergodic and outage MIMO capacities are analyzed and the correlation between signals received among antenna pairs are investigated to determine the optimal coherence distance between the spatial antennas under different angular dispersion conditions (rich and poor scattering phenomena).</p> |
