In this work, we investigate the diversity-multiplexing tradeoff (DMT) of the multiple-antenna (MIMO) static half-duplex relay channel. The relay channel is assumed to be symmetric in terms of number of antennas, i.e. the source and the destination have n antennas each, and the relay has m antennas. A general expression is derived for the DMT upper bound, which can be achieved by a compress-and-forward protocol at the relay, under certain assumptions. It is observed that the static half-duplex DMT matches the full-duplex DMT when the relay has a single antenna, and is strictly below the full-duplex DMT when the relay has multiple antennas.

Diversity-Multiplexing Tradeoff for the MIMO Static Half-Duplex Relay Leveque, Olivier; Vignat, Christophe; Yüksel Turgut, Ayşe Melda (2010-07-01) In this paper, we investigate the diversity-multiplexing tradeoff (DMT) of the multiple-antenna (MIMO) static half-duplex relay channel. A general expression is derived for the DMT upper bound, which can be achieved by a compress-and-forward protocol at the relay, under certain assumptions. The DMT expression is given as the solution of a minimization problem in general, and an explicit expression is found when the relay channel is symmetric in terms of number of antennas, i.e., the source and the destinati...
Diversity-multiplexing tradeoff in half-duplex relay systems Yüksel Turgut, Ayşe Melda; Erkip, Elza (2007-01-01) We study the multiple antenna half-duplex relay channel from the diversity-multiplexing tradeoff (DMT) perspective. We find performance upper bounds and show that compress-and-forward (CF) protocol achieves the upper bound. We argue that although it is hard to find the exact DMT expressions for decode-and-forward (DF) type protocols, they would be suboptimal in the multiple antenna case. We also study the multiple-access relay channel (MARC), and evaluate how CF works in this system. Our results show that C...
Diversity-multiplexing tradeoff in multiple-antenna relay systems Yüksel Turgut, Ayşe Melda; Erkip, Elza (2006-01-01) We study the diversity-multiplexing tradeoff (DMT) for the full-duplex relay channel when the source and the destination have multiple antennas, and the relay has I or more. We find DMT upper bounds and investigate the achievable performance of decode-and-forward (DF), partial decode-and-forward (PDF), and compress-and-forward (CF) protocols. We study the effect of increased degrees of freedom in the direct link and the source-relay channel when multiple antennas are introduced. Our results suggest that whi...
Diversity-multiplexing tradeoff in cooperative wireless systems Yüksel Turgut, Ayşe Melda; Erkip, Elza (2006-01-01) We first examine a system with a single source-destination pair and two relays, each node with a single antenna, and explore whether this virtual multi-input multi-output (MIMO) system can mimic a physical MIMO in terms of diversity-multiplexing tradeoff (DMT). We show that even under the idealistic assumption of full-duplex relays and a clustered network, the relay system can never fully mimic a real MIMO DMT, it is multiplexing gain limited. The limitation comes from the fact that source and destination a...
Gan-based robust low-noise amplifier Kazan, Oğuz; Aydın Çivi, Hatice Özlem; Koçer, Fatih; Department of Electrical and Electronics Engineering (2018) This thesis presents the theory, design and evaluation of low-noise amplifiers (LNAs) with high input power immunity, built on GaN/SiC substrate. Two separate X-band (8-12 GHz) LNAs are designed and sent out for production. After the manufactured samples are received, they are measured and evaluated. Measurement results show that both LNAs have a gain of more than 20 dB. One LNA achieves a noise figure of less than 2 dB, while the second one has a noise figure of less than 2.5 dB. Using three-stage topology...
