GPS receiver operation can be interrupted by intentional/unintentional jammers even with low power levels. As the jammers become more abundant, protection of critical systems gains importance. In this work, it is aimed to suppress the GPS L1 band jammers using spatial filtering with antenna arrays. After experimental studies, it is achieved to suppress the jammers and to recover the GPS operation in real environment.

Global Positioning System (GPS) jammers add excessive noise to the received low power GPS signals and have capability to either weaken or completely destroy the positioning performance of GPS receivers for both civilian and military users. Researchers are actively working to develop GPS receiver systems resistant to interference sources. Our aim is to develop a system based on spatial filtering of jamming signals through the use of an active antenna array which is capable to control its radiation pattern by...

Balevi, Eren; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2016)
Detection of symbols in the presence of many interference sources is a difficult task in wireless channels. It is obligatory to reduce the interference for reliable communication. In this dissertation, minimum mean square error (MMSE) detection is investigated to suppress interference. Faster Than Symbol Rate (FTSR) sampling and Frequency Domain Oversampling (FDO) methods are proposed to enhance the interference suppression level of MMSE detection for both single user and multiuser communication. The aim of...

GPS jammers add excessive noise to received low power GPS signals and have capability to weaken or completely destroy the positioning performance of GPS receivers. The most popular technique to overcome GPS jamming problem is suppression of jammers by using array signal processing techniques. In this thesis, a GPS anti-jamming system is constructed by designing an active antenna array and implementing adaptive beamforming techniques. This thesis mainly include the design of four element active circularly po...

In this paper, broadcast beamforming with relay selection is considered in wireless relay networks where there is no direct link between the source and the receivers. A source node transmits common information to many users employing multiple relays which use amplify-and-forward relay protocol. The channel state information is assumed to be available at a single relay to compute the relay weights and distribute them. Discrete relay weights are used due to several advantages including decreased overhead for ...
Method of moments analysis of slotted waveguide antenna arrays
Altuntaş, Abdülkerim; Alatan, Lale; Department of Electrical and Electronics Engineering (2014)
Slotted waveguide antenna arrays are used extensively in many applications because of their high power handling capability, planarity, low loss and reduced profile. After the synthesis of such an array, the design should be verified by analyzing the array with an efficient simulation tool which is accurate, fast and flexible. Although FEM (Finite Element Method) based commercial softwares are very accurate and flexible, they are not sufficiently fast especially when it comes to optimization and fine tuning....
