Abstract
Linear Stochastic Estimation (LSE) is a well known, widely used data analysis technique, offering quantitative insight into the dynamics of coherent structures12. In the wall-pressure based classical LSE approach the velocity estimate u(t) is obtained from the wall-pressure p(t) as u(t)_LSE = bo*p(t), i.e. by using a single sam- ple of the wall-pressure time history. By contrast, in the Multi-Time-Delay (MTD) technique more than one past samples is used simultaneously for the estimate.
