Performance of centralized and distributed estimation algorithms. A single source field (M=1) with c 1=1, τ 1=1.213, ξ 1=(0.1130,0.2210) is considered and its source parameters are estimated from the (noisy) spatiotemporal samples taken at \(\frac {1}{\Delta t} = 1\) Hz over T=10 s using N=45 sensors, with the spatial sensing function family chosen such that K=1. We show the MSE of the centralized and distributed algorithms computed using results from 5000 independent trials for varying signal-to-noise ratios in a MSE of ξ 1,1, b MSE of ξ 2,1 and c MSE τ 1
