The source data of intrusion detection system (IDS) are characteristic of heavy-flow, high-dimension and nonlinearity. A frequent problem in IDS is the choice of the right features that give rise to compact and concise representations of the network data; the other is how to improve the detection efficiency and accuracy of IDS under the small sample(More)
A relay scheme combining network coding with channel coding is proposed for multiple-access relay channel. Via a newly designed network low density parity check code, this scheme permits the relay node to jointly encode the data information from two source nodes. To predict the system performance, a newly generalized Gaussian approximation algorithm is(More)
A distance enumerator analysis is given for multiuser codes over a Gaussian multiple-access channel (MAC). A multi-user code distance is defined as the Euclidean distance between two multi-user codewords after their inter-user super-position caused by MAC. By employing a user-interleaving and a user-scrambling, a multi-user code ensemble is defined, and its(More)
