Comparison of Downconversion Techniques for Software Radio
Software radio is an enabling technology for future radio transceivers, allowing the realisation of multimode, multiband, and reconfigurable base stations and terminals. This paper describes work comparing two suitable methods of downconverting RF signals to baseband, which may be used in software radios. These are direct conversion and bandpass sampling.

Software Radio and Reconfiguration
Dynamic Re-configuration of lower layers of the protocol stacks used in communications terminals is key to the development of future multi- mode software radios. Together with the use of software downloading, future terminals will become a platform to support the deployment of yet unspecified services and applications.

Software-Defined Radios Make Their Move
The concept behind the technology is that it will provide soft-ware control of radio functionality. Traditional radio designs are constructed of fixed analog or digital components. Such designs also are custom built for each application. By comparison, SDRs offer an inherent flexibility.

A Software Defined Radio is a term used to describe a control software for a radio application which provide modulation techniques, narrow band operation or wide band, communications security functions and waveform requirements. In order to provide wide frequency distribution for different frequency bands, and antenna system is utilised using a front end switch. The concept of 'software radio' has been around for some time, having initially
