... the beamforming gain and CFO in MC- CDMA systems; second, outage probabilities are derived for MC -CDMA systems with either perfect or imperfect beam- forming in the presence of CFO. The remainder ... eliminate any noticeable cou- pling. 6. CONCLUSION The outage probability of reverse link MC -CDMA systems with beamforming in the presence of...

... nonexpansive in the intermediate sense, then T has a fixed point. It is worth mentioning that the class of mappings which are asymptotically nonexpansive in the intermediate sense contains properly the ... more details. In this paper, we consider the problem of convergence of Ishikawa iterative processes for the class of asymptotically κ-strict pseudocontractive mappi...
