Hi all,
actually i want to ask about which parameter better to use changing modulation of WiMAX on radio link, RSSI or CINR?, as i know RSSI and CINR maybe can change in different way, if RSSI degradate much, maybe CINR not (vice-versa).
We can calculate RSSI from equation in standard 802.16e (8.4.13.1.1), but how to calculate CINR (not only CNR or SNR)?
from standard there's only receiving SNR threshold for WiMAX modulation and coding rate, how about the interference?, is that same if i assume that the interference same in noise if i measure the real condition in air interface? (i mean if i have the same CINR threshold like SNR threshold?
Thanks for anyone if want to discuss
