Subspace Method-based Blind SNR Estimation for Communication between Orbiters in Mars Exploration

Subspace Method-based Blind SNR Estimation for Communication between Orbiters in Mars Exploration

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 the communication system. Therefore, SNR estimat...
