A simple way to perform computations of the useful and interference power expressions is to follow an approach similar to the approach used for MC-CDMA ... similarly affected by CFO. Hence, joint-DFT B-IFDMA provides a better robustness to multiuser interference than added-signal B-IFDMA, and so is better suited for the uplink. Then we...
