Sparsity of event related potentials (ERP) in time domain is used to develop a single trial ERP detection method. It is assumed that ERPs are deterministic whereas the ongoing EEG does not have this property . Using the recursive projected compressive sensing (Re-ProCS) method  the electroencephalogram (EEG) data is decomposed into a high dimensional, low rank component and a sparse component which represents the ERPs. The method shows promising results on EEG data which is synthetically generated using real EEG and ERP samples.
