Training-Based Schemes are Suboptimal for High Rate Asynchronous Communication

TL;DR

This paper demonstrates that training-based communication schemes, which separate synchronization from data transmission, are not optimal for high-rate asynchronous point-to-point communication.

Contribution

It provides a theoretical analysis showing the suboptimality of training-based schemes in high-rate asynchronous communication scenarios.

Findings

Training-based schemes perform suboptimally at high rates.

Separation of synchronization and data transmission is inefficient for high-rate communication.

The paper offers a model to analyze asynchronous communication strategies.

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.
