  • Wireless communications is rapidly becoming one of the ubiquitous technological underpinnings of modern society (such as electric power, fossil fuels, automobiles, etc.). Few people think about the technology within their mobile phones, remote controls, garage door openers, GPS navigation devices, and so on. They are always at hand and reliably work for the user. Yet even within the electrical engineering (EE) community, radio communication techniques have a reputation as a “Black Art” that can only be successfully practiced by “RF people”. This is changing, albeit slowly.

  • Speech coding is at the heart of digital wireless telephony. It consists of reducing the number of bits needed to represent the speech signal while maintaining acceptable quality. Digital cellular telephony began in the late 1980s at a time when speech coding had matured enough to make it possible. Speech coding has made digital telephony an attractive proposition by compressing the speech signal, thus allowing a capacity increase over analog systems.

  • Introduction To Equalizers In most digital data transmission systems the dispersive linear channel encountered exhibits amplitude and phase distortion. As a result, the received signal is contaminatedby Intersymbo1 Interference (ISI). In a system, which transmits a sequenceof pulse-shaped information symbols, the time domain full response signalling pulses are smeared hostile dispersive by the channel, resulting in intersymbol interference. At the receiver, the linearly distorted signal has to be equalized in order torecover the information.
