A Generalized Expression for the Gradient of Mutual Information with the Application in Multiple Access Channels
Mahboobeh Sedighizad, Babak Seyfe
Taking a functional approach, we derive a general expression for the gradient of the Mutual Information (MI) with respect to the system parameters in the stochastic systems. This e…
Capacity of the State-Dependent Wiretap Channel: Secure Writing on Dirty Paper
Hamid G. Bafghi, Babak Seyfe, Mahtab Mirmohseni +1
In this paper we consider the State-Dependent Wiretap Channel (SD-WC). As the main idea, we model the SD-WC as a Cognitive Interference Channel (CIC), in which the primary receiver…
On The Secrecy of the Cognitive Interference Channel with Partial Channel States
Hamid G. Bafghi, Babak Seyfe, Mahtab Mirmohseni +1
The secrecy problem in the state-dependent cognitive interference channel is considered in this paper. In our model, there are a primary and a secondary (cognitive) transmitter-rec…
Source Number Estimation via Entropy Estimation of Eigenvalues (EEE) in Gaussian and Non-Gaussian Noise
Hamid Asadi, Babak Seyfe
In this paper, a novel method based on the entropy estimation of the observation space eigenvalues is proposed to estimate the number of the sources in Gaussian and Non-Gaussian no…
On The Secrecy of the Cognitive Interference Channel with Channel State
Hamid G. Bafghi, Babak Seyfe
In this paper the secrecy problem in the cognitive statedependent interference channel is considered. In this scenario we have a primary and a cognitive transmitter-receiver pairs.…
On The Achievable Rate Region of a New Wiretap Channel With Side Information
Hamid G. Bafghi, Babak Seyfe, Mahtab Mirmohseni +1
A new applicable wiretap channel with separated side information is considered here which consist of a sender, a legitimate receiver and a wiretapper. In the considered scenario, t…
