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 ...
Space time coded cooperative communication with joint antenna and relay selection
(2010)
Although multiple antenna and cooperative communication techniques can increase the system capacity, it can be difficult to use them in practice because of their high complexity. In this paper," joint transmit/receive ...
Busy tone implementation for coexistence of IEEE 802.22 and 802.11af systems
(Institute of Electrical and Electronics Engineers Inc., 2015)
In this paper, a new algorithm based on busy tone approach has been proposed for the coexistence of IEEE 802.22 and IEEE 802.11af systems in TV white space. Different from the earlier study, in addition to 802.11af access ...
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" ...
Optimization of graph affinity matrix with heuristic methods in dimensionality reduction of hypespectral images
(Institute of Electrical and Electronics Engineers Inc., 2019)
Hyperspectral images include hundreds of spectral bands, adjacent ones of which are often highly correlated and noisy, leading to a decrease in classification performance as well as a high increase in computational time. ...
