Training-Based Schemes are Suboptimal for High Rate Asynchronous Communication

Abstract
We consider asynchronous point-to-point communication. Building on a recently developed model, we show that training based schemes, i.e., communication strategies that separate synchronization from information transmission, perform suboptimally at high rate.
