Abstract: A method includes receiving a signal over a multi-path channel, generating a plurality of observation vectors of the received signal, generating a channel covariance matrix of the plurality of observation vectors, and identifying a first path by projecting a pulse shaping vector on the channel covariance matrix at different time offsets and selecting the maximum thereof as the first path. Thereafter, further paths can be identified. In each case, an n-th path is identified by projecting the pulse shaping vector into a null space of n-1 previously identified paths at different time offsets and the maximum thereof is selected as an n-th path.
