Rayleigh block-fading
The terms slow and fast fading refer to the rate at which the magnitude and phase change imposed by the channel on the signal changes. The coherence time is a measure of the minimum time required for the magnitude change or phase change of the channel to become uncorrelated from its previous value. • Slow fading arises when the coherence time of the channel is large relative to … WebApr 11, 2024 · In Equation (), the first term is the desired symbol of subcarrier k and the second term is the distortion caused by symbols of the other subcarriers on subcarrier k due to the CFO.This term is called the inter carrier interference (ICI) term. Higher order constellations are more sensitive to system non-linearities and noise, since the symbols in …

Weband IDD schemes have dealt with quasi-static Rayleigh fading channels or fast Rayleigh fading channels. However, there are very few studies related to the case of block-fading channels with MIMO systems. To the best of our knowledge, the only study which discusses MIMO systems under block-fading channels is the work by Capirone and Tarable [33 ...
