Introduction

Software-Defined Radio (SDR) Forum defines SDR technology as radios that provide software control of a variety of modulation techniques, wide-band or narrow-band operation, communications security functions (such as hopping), and waveform requirements of current & evolving standards over a broad frequency range.

In a nutshell, Software-Defined Radio (SDR) refers to the technology wherein software modules running on a generic hardware platform consisting of DSPs and general purpose microprocessors are used to implement radio ....etc

The DRM Signal is received by a commercial long, medium, short-wave (SW, MW, LW) front-end. Any front-end should be usable which can provide an IF of 12 kHz direct or with an adapter circuit. The bandwidth must be greater 10 kHz for normal transmissions and greater 20 kHz for transmissions with channel bundling. This signal is then fed into a standard soundcard. The soundcard must offer a sampling rate of 48 kHz. For output of the audio signal also a soundcard with a sampling rate of 48 kHz is required. If one sound card is used for sampling th ....etc

A Paper Presentation on Software Development Automation by Computer Aided Software Engineering (CASE)



Abstract: Nowadays, system developers are faced to produce complex, high quality software to support the demand for new and revised computer applications. This challenge is complicated by strict resource constraints, forcing management to deploy new technologies, methods and procedures to manage this increasingly complex environment. Often the methods, procedures and technologies ar ....etc

Software componentry is a field of study within software engineering. It builds on prior theories of software objects, software architectures, software frameworks and software design patterns, and the extensive theory of object-oriented programming and object-oriented design of all these. It claims that software components, like the idea of hardware components, used for example in telecommunications, can ultimately be made interchangeable and reliable. A software component is a system element offering a predefined service and able to communicat ....etc

A software methodology consists of rules and practices for creating the computer programs. Heavyweight methodologies have a lot of such rules and practices, and many documents are produced as a result of applying these methodologies. Following these methodologies requires discipline and time, i.e. they are bureaucratic. In the last few years some new methodologies have emerged as a reaction to these disciplined methodologies. These are known agile (or lightweight) methodologies. An agile methodology has not too much rules and practices to follo ....etc

Computers are as ubiquitous as automobiles and toasters, but exploiting their capabilities still seems to require the training of a supersonic test pilot. VCR displays blinking a constant 12 noon around the world testify to this conundrum. As interactive television, palmtop diaries and smart credit cards proliferate, the gap between millions of untrained users and an equal number of sophisticated microprocessors will become even more sharply apparent. With people spending a growing proportion of their lives in front of computer ....etc

Software radio is an emerging technology, thought to
build flexible radio systems, multiservice, multistandard, multiband,
reconfigurable and reprogrammable by software. The flexibility of a
software radio system consists in its capability to operate in
multiservice environments, without being constrained to particular
standard, but able to offer, services of any already standardized
systems or future ones on radio frequency band. The presence of the
software defining the radio inter face necessarily implies the use of
DSPs to replace d ....etc
