It is a great pleasure to welcome the participants of the 32nd National Radio Science Conference in the premises of MSA University. It is also an honor for the university to organize this high profile event for the third time during the lifetime of this prestigious national conference.
In this paper, an advanced closed loop Polarized Multiple-Input Multiple-Output Pre-RAKE Combined Transmit Diversity “Pol MIMO Pre-RAKE CTD” system is proposed for the downlink. The proposed system is designed and analyzed in frequency division duplex mode. The numerical results demonstrate that it can achieve a significant performance gain, especially for dense urban and suburban environments. This...
Wireless Heterogeneous Networks (WHN) have become one of the deployment scenarios for the Fourth Generation Mobile Communications Networks (4G). In recent trends, heterogeneous service models integrating between Wireless LANs (WLANs) and cellular networks have attracted the most attention. This is due to the increasing demand for broadband services, causing cellular network providers to consider the...
WiMAX packet networks are considered an attractive broadband wireless technology for 4G networks due to the support of quality of service (QoS) they provide. Radio resource allocation is an important part of the WiMAX QoS framework and a great part of its design and implementation is left to the vendor. Current WiMAX standard defines the real time polling service (rtPS) as the polling service for...
