Error Rate and Ergodic Capacity of RF-FSO System with Partial Relay Selection in the Presence of Pointing Errors
Milica I. Petkovic, Imran Shafique Ansari, Goran T. Djordjevic +1
This paper presents an analysis of a multiple dual-hop relaying system, which is composed of km-class radio frequency (RF)-free-space optical (FSO) links. Partial relay selection b…
Performance of Opportunistic Fixed Gain Bidirectional Relaying With Outdated CSI
Fahd Ahmed Khan, Kamel Tourki, Mohamed-Slim Alouini +1
This paper studies the impact of using outdated channel state information for relay selection on the performance of a network where two sources communicate with each other via fixe…
Gaussian Assumption: the Least Favorable but the Most Useful
Sangwoo Park, Erchin Serpedin, Khalid Qaraqe
This paper focuses on three contributions. First, a connection between the result, proposed by Stoica and Babu, and the recent information theoretic results, the worst additive noi…
A Unifying Variational Perspective on Some Fundamental Information Theoretic Inequalities
Sangwoo Park, Erchin Serpedin, Khalid Qaraqe
This paper proposes a unifying variational approach for proving and extending some fundamental information theoretic inequalities. Fundamental information theory results such as ma…
Random Subcarrier Allocation in OFDM-Based Cognitive Radio Networks
Sabit Ekin, Mohamed M. Abdallah, Khalid A. Qaraqe +1
This paper investigates the performance of an orthogonal frequency-division multiplexing (OFDM)-based cognitive radio (CR) spectrum sharing communication system that assumes random…
On the equivalence between Stein and de Bruijn identities
Sangwoo Park, Erchin Serpedin, Khalid Qaraqe
This paper focuses on proving the equivalence between Stein's identity and de Bruijn's identity. Given some conditions, we prove that Stein's identity is equivalent to de Bruijn's…
An Alternative Proof of an Extremal Entropy Inequality
Sangwoo Park, Erchin Serpedin, Khalid Qaraqe
This paper first focuses on deriving an alternative approach for proving an extremal entropy inequality (EEI), originally presented in [11]. The proposed approach does not rely on…
