The transmission rate and reliability are the most crucial elements of a communication system on sea platforms. In this thesis, the performance of a high speed and reliable communication system that can be used on ship to ship sea platforms will be evaluated. The two ray channel model is used in order to characterize the channel considering the refraction and reflection. Using the channel model, the path loss and the Shannon channel capacities are obtained for different systems. In order to increase the system performance, frequency diversity technique is used and a detailed comparison of diversity combining techniques is provided. As an alternative to Shannon channel capacity, cut off rate analysis is considered to get more realistic results about the rate of the communication system in that it takes modulation into account and the results are compared with the channel capacity. Block fading model and jamming effects on the achievable rate of the system is considered for different linear modulation techniques. Finally, an OFDM system design is given as an example using the tools obtained in this work.

Solution of the antenna palcement problem by means of global optimization techniques Ural, Mustafa; Kuzuoğlu, Mustafa; Department of Electrical and Electronics Engineering (2010) In this thesis work, minimization of platform-based coupling between the antennas of two VHF radios on an aircraft platform and two HF radios on a ship platform is aimed. For this purpose; an optimal antenna placement, which yields minimum average coupling between the antennas over the whole frequency band of operation is determined for each platform. Two important global optimization techniques, namely Genetic Algorithm Optimization and Particle Swarm Optimization, are used in determination of these optima...
Efficient analysis of large array antennas Ovalı, Fatih; Aydın Çivi, Hatice Özlem; Department of Electrical and Electronics Engineering (2004) Large phased array antennas are widely used in many military and commercial applications. The analysis of large arrays containing many antenna or frequency-selective (FSS) surface elements is inefficient or intractable when brute force numerical methods are used. For the efficient analysis of such structures hybrid methods (analytic and numerical, numerical and numerical) can be used. In this thesis, a hybrid method combining the uniform geometrical theory of diffraction (UTD) and the moment method (MoM) us...
Shock analysis of an antenna structure subjected to underwater explosions Demir, Mehmet Emre; Çalışkan, Mehmet; Department of Mechanical Engineering (2015) Antenna structures constitute main parts of electronic warfare systems. Mechanical design is as crucial as electromagnetic design of antenna structures for proper functioning and meeting high system performance needs. Failure of mechanical and electronic structures operating under shock loading is a common occurrence in naval electronic warfare applications. A complete shock analysis of the dipole antenna structure subjected to underwater explosions is performed to foresee adverse effects of mechanical shoc...
Inter-connected flexray and can networks for in-vehicle communication : gateway implementation and end-to-end performance study Alkan, Melih; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2010) 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...
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...
