... frequency-flat fading channels in [12] using the channel estimation performance bound as a metric for training design. It was found that the optimal training can be achieved from an arbitrary sequence and ... have been only a few literatures on training-based AF channel estimation, and research in this area is still in its infancy. Based on the assumption of flat-fading channels...
