Soft Modems use the main processor to execute modem functions traditionally performed by hardware on the modem card. To function correctly, soft modems require that ongoing signal processing computations be performed on the host CPU in a timely manner. Thus, signal processing is a commonly occurring background real-time application—one running on systems that were not designed to support predic...

the arabic literary criticism has passed various stages up to its modem formation. each stage has its own characteristics. then through different processes of its development it reached the peak. one may notice excellent creativity, innovations, and systematic approach. of course, the experts have their own ways of calssification for these stages. some believe in detail and some in brief these ...

The exponentially-growing mobile data traffic imposes significant demands on the capacity of the mobile network. Fiber optic and microwave links are two main solutions for the mobile backhaul network, which provides connectivity between radio base station (RBS) sites and the switch sites. As compared to fiber, a microwave solution is much easier to deploy, however, its capacity is lower. This t...

As it is known, to provide fire protection for any type of surface vessel, external fire-fighting (EFF) systems have been commonly used decades as well in coastal regions. These types exist on several vessels such ships, tugboats, supply and naval vessels. Flow conditioners can be the EFF better performance by regulating flow inside fi-fi monitor. In present study, a (fi-fi) monitor was designe...

Cable networks have evolved from offering broadcast services to providing high rate two-way data services. In the next step, cable operators intend to use Voice over IP (VoIP) to provide cable telephony services. In a cable network the users are connected to the headend through a cable modem. The headend is responsible for allocating upstream bandwidth to the various cable modems. Each cable mo...

ALGORITHM FOR A NARROWBAND WIRELESS MODEM J. H. Grimm, R. N. Kumar, J. Kusuma, and J. V. Krogmeier School of Electrical and Computer Engineering Purdue University West Lafayette, IN 47907-1285 http://yake.ecn.purdue.edu/ cominfo/ ABSTRACT This paper examines some of the complexity issues arising in the real time implementation of the symbol timing subsystem of a narrowband wireless modem. The m...

Space Engineering SpA has recently developed a multi-processor, multi-FPGA (Field Programmable Gate Array), compact platform, including a multiple analog interface based on high-speed and high-accuracy ADC (Analog to Digital Converter) and DAC (Digital to Analog Converter). The platform with related software is intended to be a potentially powerful development system for the implementation of s...
