Frequency multiplexer structures are of a crucial role as an essential part of huge variety of communication systems including, satellite-communication systems, wireless communication systems and radio transmission. They are indispensable multiple port components that are used for combination and separation of specific signals or frequency bandwidths selectively from a single signal or frequency bandwidth in multiport communication system. The main blocks that form a multiplexer are a set of filters, named as channel filters, and junctions connecting to filters to the common port. In satellite-communication systems, waveguide filter structures are mostly preferred and employed as channel filter in multiplexer configuration due to the fact that they are of low insertion loss, high power handling capability and high quality factor. On the other, bulkiness and large sizes of them are troublesome in satellite-communication applications. Therefore, one of the main goals of this thesis is to design miniaturized, compact and weight-reduced channel filter structure including coupled resonators. Also, developing a framework for methodical design involving surface roughness effect and physically realizing the waveguide filter structure as a significant part of the multiplexer with lowest possible size and weight and sharp passband characteristic to be minimized the adjacent channel interference is in the main scope of this study.

Aspects of HF radio propagation
Warrington, E. Michael; Bourdillon, Alain; Benito, Eulalia; Bianchi, Cesidio; Monilie, Jean-Philippe; Muriuki, Martha; Pietrella, Marco; Rannou, Veronique; Rothkaehl, Hanna; Saillant, Stephane; Sari, Ozgur; Stocker, Alan J.; Tulunay, Ersin; Tulunay, Yurdanur; Zaalov, Nikolay Y. (2009-06-01)
The propagation characteristics of radio signals are important parameters to consider when designing and operating radio systems. From the point of view Working Group 2 of the COST 296 Action, interest lies with effects associated with propagation via the ionosphere of signals within the HF band. Several aspects are covered in this paper:
Diversity Analysis of Hierarchical Modulation in Wireless Relay Networks
Yalcyn, Ahmet Zahid; Yüksel Turgut, Ayşe Melda (2014-07-01)
In communication systems, hierarchical modulation is used to increase system robustness and to send different information flows simultaneously. However, when used in cooperative communication systems, hierarchical modulation is prone to error propagation, which is the most important problem that prevents the achievement of full diversity gains. Depending on the signal-to-noise ratio between the source and the relay, threshold digital relaying can be used to mitigate error propagation. Mitigating error propa...
Design of dual-frequency probe-fed microstrip antennas with genetic optimization algorithm
Ozgun, O; Mutlu, S; Aksun, MI; Alatan, Lale (2003-08-01)
Dual-frequency operation of antennas has become a necessity for many applications in recent wireless communication systems, such as GPS, GSM services operating at two different frequency bands, and services of PCS and IMT-2000 applications. Although there are various techniques to achieve dual-band operation from various types of microstrip antennas, there is no efficient design tool that has been incorporated with a suitable optimization algorithm. In this paper, the cavity-model based simulation tool alon...
Design of Tunable Amplifier Using Digital Capacitors
Atilla, Dogu Cagdas; Aydin, Cagatay; Nesimoglu, Tayfun; KÖPRÜ, RAMAZAN; Aksen, Ahmet; Yarman, B. S. (2014-12-14)
In recent days, radio manufacturers are increasingly interested in broadband amplifiers for cellular communication. Demands of customers enforce manufacturers to develop systems compatible for all standards and it is mandatory to accommodate more than one amplifier or tunable amplifier in front end of communication systems. In this paper, design of tunable amplifier is investigated by using Real Frequency Technique and agility of tunable components is provided by digital tunable capacitors.
EFFICIENT SIGNAL PROCESSING TECHNIQUES FOR COLOCATED MASSIVE MIMO RADCOM BASED ON OFDM WAVEFORM
GÜREŞ, SEDA; GÜVENSEN, GÖKHAN MUZAFFER; Department of Electrical and Electronics Engineering (2022-11-28)
Radar systems and communication systems play a vital role in military and commercial usage of information transmission. The concept of integration these systems in a single platform with joint waveform is called as RADCOM (Radar and Communication). MIMO structures are promising systems to provide time-frequency and space usage approach with having multiple transmit and multiple receive antennas integrated in single platform. MIMO radar transmits multiple probing signals via transmit antennas and receiving a...
