EM-MAP based initializaition of PIC receiver for downlink MC-CDMA systems
(IEEE, 2007)
The quality of multiple access interference (MAI), which can be improved by using channel estimation and data estimation of all active users, effects considerably the performance of PIC detector. Therefore, data and channel ...
A numerical method for frequency determination in the astable cellular neural networks with opposite-sign templates
(2006)
In this study, a numerical method is proposed to determine the oscillation frequencies in the astable cellular neural networks with opposite-sign templates [1]. This method depends on the training of a multilayer perceptron ...
Effect of channel estimation errors on the performance of space time coded systems with antenna selection
(2007)
This paper presents the effects of channel estimation errors on the performance, especially diversity gain, of space-time coded systems with antenna selection. We consider maximum signal to noise ratio as the antenna ...
İterative receiver for DS-CDMA systems in the presence of time-varying channels
(2008)
In this paper, we present an efficient iterative receiver structure of tractable complexity for joint multiuser detection and multichannel estimation (JDE) ofdirect-sequence code-division multiple-access systems operating ...
Analytical approaches for the amplitude and frequency computations in the astable cellular neural networks with opposite sign templates
(2007)
In this paper, by using surface fitting methods, analytical approaches for amplitudes and frequencies of the x1,2(t) "States" in a simple dynamical neural network called "Cellular Neural Network with Opposite Sign Templates" ...
Trust, confidence and e-commerce in cyberspace
(2002)
The trust, confidence and e-commerce issues in cyberspace are discussed. Development of commercial activities in the cyberspace hinges on assuring consumers and businesses that their use of network services were safe, ...
