Considerations on a frequency correlation for distributed antenna systems

In this paper, we have investigated the proposed frequency correlation for distributed antenna systems in the exponential delay profile case. It has been clarified that the frequency correlation for the 2 RAU case varies depending on the MT position. On the other hand, in the case of 7 RAUs, it has been shown that all the frequency correlations almost coincide with each other. Moreover, it has been shown that the frequency correlation and the degradation coefficient of the signal detection show almost the same behavior. Therefore, we can evaluate the degradation of the signal detection using the proposed frequency correlation.
