The communication needs of Earth observation satellites is steadily increasing. Within a few
years, the data rate of such satellites will exceed 1 Gbps, the angular resolution of sensors will be
less than 1 μrad, and the memory size of onboard data recorders will be beyond 1 Tbytes.
Compared to radio frequency links, optical communications in space offer various advantages
such as smaller and lighter equipment, higher data rates, limited risk of interference with other
communications systems, and the effective use of freque ....etc

Resource Allocation in OFDMA Wireless Communications Systems Supporting Multimedia Services



Abstract:
We design a resource allocation algorithm for downlink of orthogonal frequency division multiple access (OFDMA) systems supporting real-time (RT) and best-effort (BE) services simultaneously over a time-varying wireless channel. The proposed algorithm aims at maximizing system throughput while satisfying quality of service (QOS) requirements of the RT and BE service ....etc

RESOURCE ALLOCATION IN OFDMA WIRELESS COMMUNICATIONS SYSTEMS SUPPORTING MULTIMEDIA SERVICES- NETWORKING

We design a resource allocation algorithm for down-link of orthogonal frequency division multiple access (OFDMA) systems supporting real-time (RT) and best-effort (BE) services simultaneously over a time-varying wireless channel. The proposed algorithm aims at maximizing system throughput while satisfying quality of service (QoS) requirements of the RT and BE services. We take two kinds of QoS requirements into account. One is the require ....etc

ABSTRACT

With the ever growing demand of data applications, traditional cellular networks face the challenges of providing enhanced system capacity, extended cell coverage, and improved minimum throughput in a cost-effective manner. Wireless relay stations, especially when operating in a halfduplex operation; make it possible without incurring hi ....etc

Advanced technologies for 4G: Mobile broadband multimedia everywhere


Changing the wireless experience
The drive to 4G is being fueled by the promise of target peak data rates of
approximately 1 Gigabit per second
(Gbit/s) for low mobility (such as nomadic/local wireless access) and approximately 100 Megabits per second (Mbit/s) for high mobility (such as vehicular mobility). These data rates are part of the International Telecommunication Union (ITU) long-t ....etc

Fuzzy Logic Applications in Wireless Communications
Various areas pertaining to wireless communication systems utilize fuzzy logic. It is very much useful in modeling the problems in which all the inputs are not known or are impossible to obtain. The fuzzy logic can be easily applied to non-linear and time-variant systems and address the complex problems in this domain. Reduction in complexity and robustness can be achieved by the use of fuzzy logic. Human expert knowledge is incorporated into a rule-based framework by the fuzzy logic. ....etc
