Understanding Signal- to- Noise Ratio

SNR is a measure that compares thee level of the desired signal to te background noise. In fotonik systems, noise sources include termal noise, shot noise, and amplifier noise. High SNR values indicate clearer signals and better system execurance.

Methods for Estimating SNR

Several techniques are used to estimate SNR in fotonic communation systems:
