A new blind adaptive multiuser DETECTION scheme based on a hybrid of Kalman filter and
subspace estimation is proposed. It is shown that the detector can be expressed as an anchored
signal in the signal subspace and the coefficients can be estimated by the Kalman filter using only
the signature waveform and the timing of the desired user.
Intrusion DETECTION：Host-based Network
Intrusion DETECTION
• At each host, monitor all incoming and
outgoing network traffic – for each packet:
– Analyze 4-tuple and protocol
– Examine contents
