Table 3.

Simulation results when the length of the acquisition is varied. Shown are the k-means centroids for the fully sampled simulation data, at a fixed SNR of 5.6 (compare with the results in Table 1). The length of the signals and the dictionary were varied from 250 time points up to 2000, where the results in Table 1 correspond to signal length of 3000 time points.
