Alkan, Melih
The increasing use of electronic components in today’s automobiles demands more powerful in-vehicle network communication protocols. FlexRay protocol, which is expected to be the de-facto standard in the near future, is a deterministic, fault tolerant and fast protocol designed for in vehicle communication. The current de-facto in-vehicle communication standard, CAN, and the future in-vehicle communication standard FlexRay will exist together in future cars. Data exchange between these two standards will be performed via Gateway units. In this thesis, end-to-end performance of a FlexRay-CAN network connected by a Gateway is evaluated as well as Gateway functionality and processing delay. The results of the experiments, which are performed for a realistic message set with various scheduling schemes, are presented and discussed.

Software tool development for the automated configuration of flexray networks for in vehicle communication
Öztürk, Can; Schmidt, Şenan Ece; Schmidt, Klaus Werner; Department of Electrical and Electronics Engineering (2013)
The increasing use of electronic components in today’s automobiles demands more powerful in-vehicle network communication protocols. FlexRay protocol, which is expected to be the de-facto standard in the near future, is a deterministic, fault tolerant and fast protocol designed for in vehicle communication. For proper operation of a FlexRay network the communication schedule needs to be computed and the nodes need to be configured before startup. Current software tools that are geared towards FlexRay only d...
Fully digital parallel operated switch-mode power supply modules for telecommunications
Kutluay, Koray; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2005)
Digitally-controlled, high power universal telecommunication power supply modules have been developed. In this work, the converter control strategy, and its design and implementation first, by means of parallel-operated, dual, 8-bit microcontrollers, and then by using a high processing power digital signal processor (DSP) have been emphasized. The proposed dual-processor based digital controller provides an extended operating output voltage range of the power supplies, user programmable current limit settin...
S-band hybrid 4 bit phase shifter using cots components
Erkek, Eser; Demir, Şimşek; Department of Electrical and Electronics Engineering (2009)
Microwave and millimeter-wave phase shifters are one of the most important structures of the antenna series that are used in communication and radar applications. They are used to form the main beam of the electronically scanned phase array antennas and generate the appropriate phase values for the antenna elements design while providing electronic beam steering. In this thesis, S-band hybrid 4 bit phase shifter of 22.5º phase resolution is designed, simulated, fabricated and measured. Bits are separately d...
Cluster based user scheduling schemes to exploit multiuser diversity in wireless broadcast channels
Soydan, Yusuf; Candan, Çağatay; Department of Electrical and Electronics Engineering (2008)
Diversity methods are used to improve the reliability of the communication between transmitter and receiver. These methods use redundancy to reduce the errors in the communication link. Apart from the conventional diversity methods, multiuser diversity has an aim of maximizing the sum capacity of a multi-user system. To benefit from multiuser diversity, the opportunistic scheduling method grants the channel access to the user which has the best channel quality among all users. Therefore, the cumulative sum ...
