Guaranteeing Secrecy using Artificial Noise
Satashu Goel,Rohit Negi +1 more
TL;DR: This paper considers the problem of secret communication between two nodes, over a fading wireless medium, in the presence of a passive eavesdropper, and assumes that the transmitter and its helpers (amplifying relays) have more antennas than the eavesdroppers.
Journal ArticleDOI
Effective capacity: a wireless link model for support of quality of service
Dapeng Wu,Rohit Negi +1 more
TL;DR: This paper proposes and develops a link-layer channel model termed effective capacity (EC), which first model a wireless link by two EC functions, namely, the probability of nonempty buffer, and the QoS exponent of a connection, and proposes a simple and efficient algorithm to estimate these EC functions.
Journal ArticleDOI
Pilot tone selection for channel estimation in a mobile OFDM system
Rohit Negi,John M. Cioffi +1 more
TL;DR: In this article, it was shown that the best set of tones to be used are those which are equally spaced, rather than using all tones as pilot tones in some symbols, and that it is more efficient to use a few tones in all symbols.
Proceedings ArticleDOI
Secret communication using artificial noise
Rohit Negi,Satashu Goel +1 more
TL;DR: It is shown that secrecy can be achieved by adding artificially generated noise to the information bearing signal such that it does not degrade the intended receiver's channel.
Proceedings ArticleDOI
Combined ML and DFE decoding for the V-BLAST system
TL;DR: This paper proposes to combine maximum-likelihood decoding and decision feedback equalization (DFE) for the Vertical Bell Laboratories Layered Space-Time (V-BLAST) system, and proposes an ordering scheme which gives the best performance for the worst subchannel.
