Subspace Method-based Blind SNR Estimation for Communication between Orbiters in Mars Exploration
ITM Web of Conferences, 2017 In Mars exploration the effective time of communication between orbiters is short, and the relative distance and gesture between them change fast. The signal to noise ratio (SNR) estimation is required in receiver to change adaptively the data rate in ...

A non-data-aided SNR estimator based on maximum likelihood method for communication between orbiters
EURASIP Journal on Wireless Communications and Networking, 2020 Signal-to-noise ratio (SNR) is an important metric for performance assessment in numerous scenerios. In order to ensure the reliability and effectiveness of the system performance, plenty of situations require the information of SNR estimate. At the same

Pilot-Based Time Domain SNR Estimation for Broadcasting OFDM Systems
Journal of Computer Networks and Communications, 2018 The estimation of signal-to-noise ratio (SNR) is a major issue in wireless orthogonal frequency-division multiplexing (OFDM) system. In OFDM system, each frame starts with a preamble symbol that facilitates the SNR estimation. However, the performance of
