A 128-bit microprocessor compatible programmable correlator chip for use in synchronous communication
(IEEE, 1989)A single-chip microprocessor-compatible 128-b correlator is designed and implemented in a 3-μm M2CMOS process. Full-custom design techniques are applied to achieve the best tradeoff among chip size, speed, and power ... -
Computer aided frequency planning for the radio and TV broadcasts
(Institute of Electrical and Electronics Engineers, 1996-06)The frequency planning of the VHF and UHF broadcasts in Turkey is described. This planning is done with the aid of computer databases and digital terrain map. The frequency offset is applied whenever applicable to increase ... -

Design of an emergency PMR network based on CDMA 450 in İstanbul metropolitan region
(TEHOSS, 2006)In this work, a complete design of PMR (Professional Mobile Radio) network based on CDMA 450 in ˙Istanbul metropolitan region is presented. Coverage and capacity analysis are performed by the developed simulation software ... -
The effect of terrain roughness in the microwave line-of-sight multipath fading estimation based on Rec. ITU-R P.530-15
(IEEE, 2014-08)Multipath fading is an important constraint on the prediction of path loss for terrestrial line-of-sight microwave links. The International Telecommunication Union - Radiocommunication (ITU-R) Rec. P.530 [1] is one of the ... -
Feasibility study of installation of solar panels on a high power HF antenna land
(John Wiley and Sons Inc., 2016)In HF broadcasting, the transmitters are typically very powerful. In the case of Turkish Radio and Television (TRT), total transmission average power may reach up to 5 MW. Therefore, it is natural to utilize solar panels ... -

Multipath fading effect on terrestrial microwave LOS radio links
(IEEE, 2015-07)In this paper, the calculation of both the total received power with the effect of the ground reflection and the fade margin to find out the link availability for terrestrial microwave LOS (line-of-sight) radio links is ... -
A new approach to diffraction modelling for line-of-sight (LOS) paths
(IEEE, 2015)In this paper, we present a new knife-edge diffraction method based on Bullington method for the terrestrial line-of-sight (LOS) paths. The diffraction loss of our new knife-edge diffraction method is compared with the ... -
Outdoor propagation models: applications and considerations for real life problems
(IEEE, 2003)Implementation of propagation prediction models is discussed. It is shown that for real terrain and building data, the additional parameters and assumptions must be made. The determination of coverage percentages for digital ... -
PLAWE: A piecewise linear circuit simulator using asymptotic waveform evaluation
(Bilkent University, 1994)A new circuit simulation program, PLAWE, is developed for the transient analysis of VLSI circuits. PLAWE uses Asymptotic Waveform Evaluation (AWE) technique, which is a new method to analyze linear(ized) circuits, and ... -
Propagation prediction and planning tools for digital and analog terrestrial broadcasting and land mobile services
(2000)The problem of efficient utilization of the radiofrequency spectrum is becoming more complex due to the increasing demands on the spectrum, which is a limited natural resource. If this natural resource is to be used ...
