- The paper considers an OFDMA scheme based on OQAM/FBMC and evaluates the interaction of the different users to one another under strong frequency selectivity or timing synchronization errors between users. More specifically, due to imperfect equalization, each user contributes to a distortion component in the received signal. Such a distortion affects both its assigned subcarriers as well as others'. The distortion analytical expression shows the relationship between the prototype pulses and the number of affected out-band subcarriers. Realistic study cases show that OQAM/FBMC is a suitable solution for OFDMA schemes, since distortion can be maintained at tolerable levels.
