The first stepping stone in migration path to third generation wireless mobile services (3G) is the General Packet Radio Services, GPRS, a packet-switched technology that delivers speeds of up to 115kbps. If GPRS is already in place, Enhanced Data rates for Global Evolution (EDGE) technology is most effective as the second stepping stone that gives a low impact migration. Only software upgrades and EDGE plug-in transceiver units are needed. The approach protects operators' investments by allowing them to reuse their existing network equipment a ....etc

Driving Optical Network Evolution

Over the years, advancement in technologies has improved transmission limitations, the number of wavelengths we can send down a piece of fiber, performance, amplification techniques, and protection and redundancy of the network. When people have described and spoken at length about optical networks, they have typically limited the discussion of optical network technology to providing physical-layer connectivity. When actual network services are discussed, optical t ....etc

Wideband Sigma Delta PLL Modulator

The proliferation of wireless products over past few years has been rapidly increasing. New wireless standards such as GPRS and HSCSD have brought new challenges to wireless transceiver design. One pivotal component of transceiver is frequency synthesizer.

Two major requirements in mobile applications are efficient utilization of frequency spectrum by narrowing the channel spacing and fast switching for high data rates. This can be achieved by using fractional- ....etc

Abstract
Differential Evolution Algorithm is discussed. The design of a linear phase FIR Filter using DIFFERENTIAL EVOLUTION Algorithm is proposed. The frequency response of the designed LOW PASS FIR filter using Differential Evolution for different population and iterations are realized and compared. The best obtained filter can be used as a pulse-shaping filt ....etc
