In this thesis, various pilot symbol aided channel estimation and tracking methods are investigated and their performances are compared for an OFDM system with packet based communication on HF channel. For the HF channel, Watterson HF channel model is used. The compared methods are least squares (LS) channel estimation, linear minimum mean square error (LMMSE) channel estimation, least mean squares (LMS) channel tracking, recursive least squares (RLS) channel tracking, constant position model based Kalman filter channel tracking, and constant velocity model based Kalman filter channel tracking. For LMS and RLS methods some adaptive approaches are also investigated.

Blind channel estimation in OFDM systems Ayas, Mehmet Akif; Diker Yücel, Melek; Department of Electrical and Electronics Engineering (2015) In this thesis, we have studied blind channel estimation methods for single-input-multiple-output (SIMO) orthogonal frequency division multiplexing (OFDM) systems in time and frequency domain, in which the cross relation between the channel gains and a single snapshot of the received signal on each subcarrier is utilized. We have performed blind channel estimation for uncorrelated and correlated Rayleigh fading channel pairs using time and frequency methods in OFDM systems with one-transmitting, two-receivi...
Graph-based joint channel estimation and data detection for large-scale multiuser MIMO-OFDM systems / Tekin, Şeref Yaşar; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2015) In this thesis, a graph-based soft iterative receiver for large-scale multiuser MIMO-OFDM systems is proposed that performs joint channel estimation and data detection over time-varying frequency selective channel. In an uplink scenario, factor graph structures for the transmitter of users and the receiver of base-station are presented, which provide Gaussian message passing between nodes. Instead of LLR, reliability information of symbols are used to decrease complexity of the proposed algorithm. Training ...
On the Carrier Frequency Offset Estimation for Frequency Hopping Burst Mode Mobile Radio Güvensen, Gökhan Muzaffer; Tanık, Yalçın; Yılmaz, Ali Özgür (2010-11-03) In this paper, we evaluate the Cramer-Rao bounds (CRB) for the estimation of the carrier frequency offset (CFO) for general QAM modulations with no knowledge of the transmitted sequence (blind operation) in frequency hopping (FH) based short burst mode mobile radios. We investigate the blind CFO estimation problem in FH based mobile system that uses multiple short narrowband bursts in different frequency channels for the transmission of one packet. Joint blind channel and CFO estimation over multiple freque...
An Adaptive-Iterative Nonlinear Interference Cancellation in Time-Varying Full-Duplex Channels Kurt, Anıl; Salman, Murat Babek; Saraç, Uğur Berkay; Güvensen, Gökhan Muzaffer (2022-01-01) In this paper, first, the sensitivity of traditional Full-Duplex (FD) communication systems to time variation in the self-interference (SI) channel is demonstrated via performance analysis. It is seen that conventional schemes are not capable of providing efficient operation regarding practical concerns such as spectral efficiency, SI channel aging and learning accuracy, and the contamination of signal-of-interest (SoI). Then, in regard to the aforementioned concerns, a practical FD operation together with ...
A Secure Communication Game With a Relay Helping the Eavesdropper Yüksel Turgut, Ayşe Melda; Liu, Xi; Erkip, Elza (2011-09-01) In this work, a four-terminal complex Gaussian network composed of a source, a destination, an eavesdropper, and a jammer relay is studied under two different set of assumptions: 1) The jammer relay does not hear the source transmission, and 2) The jammer relay is causally given the source message. In both cases, the jammer relay assists the eavesdropper and aims to decrease the achievable secrecy rates. The source, on the other hand, aims to increase it. To help the eavesdropper, the jammer relay can use p...
