Distributed estimation over parallel fading channels with channel estimation error
Şenol, Habib; Tepedelenlioğlu, Cihan (IEEE, 2008)We consider distributed estimation of a source observed by sensors in additive Gaussian noise where the sensors are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. We adopt a ... -
Distributed estimation with channel estimation error over orthogonal fading channels
Şenol, Habib; Tepedelenlioğlu, Cihan (IEEE, 2007)We study distributed estimation of a source corrupted by an additive Gaussian noise and observed by sensors which are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. The fading ... -
Effect of the Channel Estimation Error on the Performance of the Source Estimator in a Wireless Sensor Network with Orthogonal Channels
Şenol, Habib; Tepedelenlioğlu, Cihan (IEEE, 2008)In this work effect of the channel estimation error on the MSE performance of the source estimator in a wireless sensor network with orthogonal flat fading channels is studied. A two-phase approach was employed where in ... -
Optimal Power Allocation Between Training and Data for MIMO Two-Way Relay Channels
Li, Xiaofeng; Tepedelenlioğlu, Cihan; Şenol, Habib (IEEE-INST Electrical Electronics Engineers Inc, 2015)Power allocation between training and data in MIMO two-way relay systems is proposed which takes into consideration both the symmetric and asymmetric cases of the two sources. For the former we present a closed form for ... -
Outage Diversity for Distributed Estimation over Parallel Fading Channels
Bai, Kai; Tepedelenlioğlu, Cihan; Şenol, Habib (IEEE, 2008)In this paper we study the outage diversity in distributed estimation over parallel fading channels. We find tight upper and lower bounds on the diversity order and show that they are arbitrarily close under certain ... -
Outage Scaling Laws and Diversity for Distributed Estimation Over Parallel Fading Channels
Bai, Kai; Şenol, Habib; Tepedelenlioğlu, Cihan (IEEE, 2009)We consider scaling laws of the outage for distributed estimation problems over fading channels with respect to the total power and the number of sensors. Using a definition of diversity which involves a fixed number of ... -
Scaling Laws For Distributed Estimation Over Orthogonal Fading Channels
Şenol, Habib; Tepedelenlioğlu, Cihan; Bai, Kai (IEEE, 2009)We analyze the outage for distributed estimation over orthogonal fading channels as a function of the number of sensors K. We consider a scenario of fixed power per-sensor with an asymptotically large number of sensors. ... -
Subspace-Based Estimation of Rapidly Varying Mobile Channels for OFDM Systems
Şenol, Habib; Tepedelenlioğlu, Cihan (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2021)It is well-known that time-varying channels can provide time diversity and improve error rate performance compared to time-invariant fading channels. However, exploiting time diversity requires very accurate channel estimates ...
