That is, the users do not operate under the same conditions.
Some users are more and some are less disturbed by multiuser interference on average.
It implies that the signals of users transmitting at identical signal to noise ratios may be characterized by di erent SINRs after multiuser detection and average channel capacities di er among the users. That is, the users do not operate under the same conditions. Some users are more and some are less disturbed by multiuser interference in the average. 11 may be characterized by di erent signal to distortion ratios after multiuser equalization. Chun C. Chan and Stephen V. Hanly.
