Performance Analysis of Energy Detection over Mixture Gamma based Fading Channels with Diversity Reception
Omar Alhussein, Ahmed Al Hammadi, Paschalis C. Sofotasios +4
The present paper is devoted to the evaluation of energy detection based spectrum sensing over different multipath fading and shadowing conditions. This is realized by means of a u…
K-Means Fingerprint Clustering for Low-Complexity Floor Estimation in Indoor Mobile Localization
Alireza Razavi, Mikko Valkama, Elena-Simona Lohan
Indoor localization in multi-floor buildings is an important research problem. Finding the correct floor, in a fast and efficient manner, in a shopping mall or an unknown universit…
Compressive Identification of Active OFDM Subcarriers in Presence of Timing Offset
Alireza Razavi, Mikko Valkama, Danijela Cabric
In this paper we study the problem of identifying active subcarriers in an OFDM signal from compressive measurements sampled at sub-Nyquist rate. The problem is of importance in Co…
Entropy and Channel Capacity under Optimum Power and Rate Adaptation over Generalized Fading Conditions
Paschalis C. Sofotasios, Sami Muhaidat, Mikko Valkama +2
Accurate fading characterization and channel capacity determination are of paramount importance in both conventional and emerging communication systems. The present work addresses…
Compressive Detection of Random Subspace Signals
Alireza Razavi, Mikko Valkama, Danijela Cabric
The problem of compressive detection of random subspace signals is studied. We consider signals modeled as where is an $N \times K…
Solutions to Integrals Involving the Marcum Q-Function and Applications
Paschalis C. Sofotasios, Sami Muhaidat, George K. Karagiannidis +1
Novel analytic solutions are derived for integrals that involve the generalized Marcum Q-function, exponential functions and arbitrary powers. Simple closed-form expressions are al…
Analytic solutions to a Marcum Q-function-based integral and application in energy detection of unknown signals over multipath fading channels
Paschalis C. Sofotasios, Mikko Valkama, Theodoros A. Tsiftsis +3
This work presents analytic solutions for a useful integral in wireless communications, which involves the Marcum function in combination with an exponential function and arb…
The Area Under a Receiver Operating Characteristic Curve Over Enriched Multipath Fading Conditions
Paschalis C. Sofotasios, Mulugeta K. Fikadu, Khuong Ho-Van +2
This work is devoted to the analysis of the performance of energy detection based spectrum sensing in the presence of enriched fading conditions which are distinct for the large nu…
Wideband Self-Adaptive RF Cancellation Circuit for Full-Duplex Radio: Operating Principle and Measurements
Timo Huusari, Yang-Seok Choi, Petteri Liikkanen +3
This paper presents a novel RF circuit architecture for self-interference cancellation in inband full-duplex radio transceivers. The developed canceller is able to provide wideband…
