Outage performance and DMT analysis of DF parallel relaying in FSO IM/DD communications
(IEEE, 2012)
In this paper, we investigate the performance of cooperative diversity transmission in free-space optical (FSO) communications. We consider an FSO cooperative diversity system with a single decode-and-forward relay and a ...
Outage performance of FSO multi-hop parallel relaying
(IEEE, 2012)
In this paper, we investigate the outage performance of relay-assisted free-space optical (FSO) networks which build upon the combinations of serial and parallel relaying. We assume log-normal atmospheric turbulence channels ...
3B kamera takibi için eylemsizlik algılayıcılarının birleştirilmesi
(IEEE, 2012)
It is well known in a Bayesian filtering framework, the use of inertial sensors such as accelerometers and gyroscopes improves 3D tracking performance compared to using camera measurements only. The performance improvement ...
Sensing-throughput tradeoff in cooperative spectrum sensing
(IEEE, 2012)
In the current literature on cognitive radio, it is commonly assumed that fixed time durations are assigned for spectrum sensing and data transmission. It is however possible to improve the performance by finding the best ...
Fast parallel prefix logic circuits for n2n round-robin arbitration
(Elsevier, 2012-08)
An n2n round-robin arbiter (RRA) searches its n inputs for a 1, starting from the highest-priority input. It picks the first 1 and outputs its index in one-hot encoding. RRA aims to be fair to its inputs and maintains ...
Dağıtık bir openflow kontrol birimi mimarisi
(IEEE, 2012)
Considering the modern internet traffic rates, the network architecture is of particular importance as the running services itself. On the other hand, due to the increasing complexity and black-box structure of the available ...
Spectrum sensing of correlated subbands with colored noise in cognitive radios
(IEEE, 2012)
In this paper, we consider the problem of wideband spectrum sensing by using the correlation among the observation samples in different subbands. The Primary User (PU) signal samples in occupied subbands are assumed to be ...
Information theoretic analysis of hybrid-ARQ protocols in coherent free-space optical systems
(IEEE, 2012-05)
Automatic retransmission request (ARQ) is a feedback-based data link layer technique which enhances the reliability of communication in fading channels. In this paper, we investigate the performance of hybrid-ARQ (H-ARQ) ...
Channel estimation in underwater cooperative OFDM system with amplify-and-forward relaying
(IEEE, 2012)
This paper is concerned with a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the resence of sparse underwater acoustic ...
Achievable data rates and power allocation for frequency-selective fading relay channels with imperfect channel estimation
(Springer Science+Business Media, 2012-12)
In this article, we investigate the information-theoretical performance of a cooperative orthogonal frequency division multiplexing (OFDM) system with imperfect channel estimation. Assuming the deployment of training-aided ...
