Effect of channel estimation errors on the performance of space time coded systems with antenna selection
(IEEE, 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 selection ...
Joint data detection and channel estimation for uplink MC-CDMA systems over frequency selective channels
(Springer, 2007)
This paper is concerned with joint channel estimation and data detection for uplink multicarrier code-division multiple-access (MC-CDMA) systems ill the presence of frequency fading channel. The detection and estimation ...
Advanced signal processing algorithms for wireless communications
(Springer-Verlag Berlin, 2006)
Traditional wireless technologies are not well suited to meet the extremely demanding requirements of providing the very high data rates with the ubiquity mobility and portability characteristic of cellular systems. Some ...
Transitional Butterworth-Chebyshev Filters
(IEEE, 2019)
Filters which are studied in this paper have properties that lie between those of the Butterworth and Chebyshev filters. So it is appropriate to call this kind of filters as transitional Butterworth-Chebyshev filters. In ...
Liquid-liquid equilibria of water+propionic acid+solvent ternaries at 298.2 K
(2006)
(Liquid + liquid) equilibrium (LLE) data for (water + propionic acid + solvent) were measured at T= 298.2 K and atmospheric pressure. The solvents were methyl isoamyl ketone (5-methyl-2-hexanone) and diisobutyl ketone. The ...
UNIFAC application to water-1-propanol-n-amyl alcohol and n-amyl acetate ternaries
(2006)
Liquid-liquid equilibrium (LLE) data for water-1-propanol-n-amyl alcohol and water-1-propanol-n-amyl acetate ternaries were measured at T=298.2 K. The UNIFAC model was used to correlate the experimental data. A comparison ...
A new approach for coexistence of IEEE 802.11af and IEEE 802.22 systems
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper various algorithms are proposed to help IEEE 802.11af and IEEE 802.22 wireless systems to coexist in TV white space by considering multiple techniques. By using busy tone power control and multihop communication ...
Real frequency design of Pi and T matching networks with complex terminations
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper real frequency design of Pi and T matching networks with complex terminations is studied. Generally the generator and load termination impedances are given as measurement values. So they can be regarded as a ...
Flexible radio resource allocation for machine type communications in 5G cellular networks
(Institute of Electrical and Electronics Engineers Inc., 2018)
The fast growth of machine-to-machine (M2M) communications in cellular networks brings the challenge of satisfying diverse Quality-of-Service (QoS) requirements of massive number of machine type communications (MTC) devices ...
Sparse Channel Estimation for Space-Time Block Coded OFDM-Based Underwater Acoustic Channels
(Institute of Electrical and Electronics Engineers Inc., 2018)
Communication over acoustic signals underwater results in multi-scale multi-lag channels due to multipath propagation. Hence a robust channel estimation technique has to be present at the receiver. In this paper assuming ...
