Abstract EN

The study and evaluation of digital communication systems in low signal-to-noise power ratio (LSNR) environments is a hot and important topic due to its wide contemporary applications.

This review is an attempt to focus on the most distinctive vital parameters required in the analysis and design of such systems.

It includes a brief literature survey for many algorithms, techniques, methodologies, and mitigations that have been used to overcome the high noise problem encountered in these systems in order to guarantee reliable communication.

Amongst these topics, the study reviews the most widely utilized modulation techniques in LSNR communication systems such as the On-Off Keying (OOK) and binary PSK schemes.

The capacity for both AWGN and wireless fading channels is also discussed along with a clarification of the minimum limits in these types of channels.

On the other hand, some important and recommended detection and estimation techniques for low power communication systems are briefly covered.

This unified study has additionally discussed spectral efficiency and bit energy trade-off within the low-power, and broadband systems, and different limitations are stated clearly.

Finally, the survey throughout this paper recommends some significant techniques that can be used in the analysis and design of successful communication systems in LSNR regimes.
