This research investigates the impact of Rician fading and correlation on the capacity and diversity of MIMO channels. If the propagation medium contains rich scattering or Rayleigh fading and the antenna arrays on both sides are uncorrelated, using antenna arrays on both sides of a wireless communication link (MIMO systems) can boost channel capacity. On the other hand, the presence of a line-of-sight (LOS) component and the correlation of real-world wireless channels may affect system performance. We also look into power distribution methods for higher capacity increases and the influence of CSI at the transmitter on capacity for SNR range. Our study examines capacity gain as a function of antenna number and signal-to-noise (SNR) power ratio. The effect of the Rician factor (L) and the correlation parameter () on the capacity and diversity gains of MIMO channels is investigated using a block and frequency nonselective Rician fading channel.
