Effect of the number of snapshots on the SINR of adaptive DBF system
Xiaoping Zeng · Journal of Chongqing University. English Edition · 2007
In the most algorithms of adaptive DBF,the number of the snapshots used to estimate the covariance matrix decides the estimation error directly,and it also effects the SINR of the system.The relationship between the number of snapshots and SINR are present here with maximum likelihood estimation and spatial smoothing estimation algorithms,which is important for the system designer to take the right number of snapshots.
