# A Comment on "A New Degree of Freedom For Energy Efficiency of Digital Communication Systems"

## TL;DR

This paper critiques a recent random number modulation scheme, highlighting its error propagation issues and arguing that minimal energy consumption is achieved by transmitting all bits rapidly with low latency.

## Contribution

It provides a critical analysis of the RNM scheme, emphasizing its drawbacks and proposing that maximum speed and minimal latency optimize energy efficiency.

## Key findings

- RNM suffers from severe error propagation
- Energy is minimized with fast, low-latency transmission
- Critique of existing encoding schemes

## Abstract

This comment recalls a previously proposed encoding scheme involving two synchronized random number generators (RNGs) to compress the transmission message. It is also claimed that the recently proposed random number modulation (RNM) scheme suffers considerably from the severe error propagation, and that, in general, the overall energy consumption is minimized when all information bits are transmitted as fast as possible with the minimum latency.
