We consider adaptive modulation and coding for channels with pilot symbol assisted modulation. Unlike most adaptive transmission schemes, we do not have any channel side information at the sender. The sender adapts not to the state of the physical chan-nel traversed by its transmitted signal, but to the quality of the measurement aorded by pilot symbols at the receiver. We consider the case where no pilot symbols are used, where pilot symbols are used with adaptive reception but without adaptive transmission, and the case where both reception and transmission are done adaptively (while main-taining the average per symbol energy constant). Our results are in terms of capacity for binary signaling. We show that, under appropriate optimizing c...
