| JADER | Blind separation of real signals using JADE (v1.5, Dec. 1997). |
| Usage: | >> B = jader(X); >> B = jader(X,m); |
| Notes: | 1) If X is an nxT data matrix (n sensors, T samples) then B=jader(X) is a nxn separating matrix such that S=B*X is an nxT matrix of estimated source signals. 2) If B=jader(X,m), then B has size mxn so that only m sources are extracted. This is done by restricting the operation of jader to the m first principal components. 3) Also, the rows of B are ordered such that the columns of pinv(B) are in order of decreasing norm; this has the effect that the `most energetically significant' components appear first in the rows of S=B*X. |
