In the paper, is discussed a MIMO-OFDM system over the frequency self-correlation of i.i.d. Rayleigh
channels and subcarrier grouping. in this paper is shown the following figure.
it shows the self-correlations of different fading environments.
Questions:
- It is shown autocorrelation function in this figure, isnt?
- What conlusion can I do accroding to this figure?
