Cooperative Spectrum Sensing in Multiple Antenna Based Cognitive Radio Network Using an Improved Energy Detector
Performance of cooperative spectrum sensing with multiple antennas at each cognitive radio (CR) is discussed in this paper. Expand
Cooperative spectrum sensing with an improved energy detector in cognitive radio network
We minimize sum of the probability of false alarm and missed detection in cooperative spectrum sensing to obtain an optimized number of CRs for detecting a spectrum hole. Expand
Performance Analysis of Gamma–Gamma Fading FSO MIMO Links With Pointing Errors
The bit error rate (BER) performance of the free space optical (FSO) link suffers from the atmospheric turbulence. By employing additional transmit and receive apertures at the transmitter andExpand
Performance Analysis of AF Based Hybrid Satellite-Terrestrial Cooperative Network over Generalized Fading Channels
We address the problem of amplify-and-forward (AF) relaying in a hybrid satellite-terrestrial link where a masked destination node receives the relayed transmission from a terrestrial link and direct transmission from the satellite link. Expand
Optimization of Cooperative Spectrum Sensing with an Improved Energy Detector over Imperfect Reporting Channels
Optimization of cooperative spectrum sensing with an improved energy detector in each cognitive radio over imperfect reporting channels is discussed in this paper. Expand
On the Closed-Form Performance Analysis of Maximal Ratio Combining in Shadowed-Rician Fading LMS Channels
In this paper, we derive approximate closed-form expressions of the probability density function and cumulative distribution function of the received signal-to-noise ratio of the MRC based receiver in SR fading LMS channels. Expand
ML Decoder for Decode-and-Forward Based Cooperative Communication System
We derive a maximum-likelihood (ML) decoder for DF protocol utilizing arbitrary complex-valued constellations including M-PSK, M-PAM, and M-QAM. Expand

We study two-way satellite relaying between two earth stations (ESs) willing to exchange their signals via a satellite. Expand
Performance evaluation of space shift keying in free-space optical communication
In this paper, we study the performance of a space shift keying (SSK) scheme in a free space optical (FSO) communication system under indoor and outdoor conditions. Expand
Performance Analysis of Cluster-Based Multi-Hop Underlay CRNs Using Max-Link-Selection Protocol
In this paper, we study the performance of a cluster-based multihop underlay cognitive radio network using an ad-hoc routing protocol (called max-link-selection protocol) with decode-and-forward relays over Rayleigh fading channels. Expand
