PARIS RadioScape, a U.K.-based developer of software-defined radios, is launching at this week's Digital Radio Show in London a new digital radio module, called RS500, capable of receiving Digital Radio Mondiale, Digital Audio Broadcast (DAB), FM with Radio Data System, Long Wave, Medium Wave and Short Wave.
RadioScape is adding to Texas Instruments' 55X core-based DSP for its new baseband software stack for Digital Radio Mondiale a global standard digital broadcasts in the AM (SW, MW and LW) frequency bands.
"We are taking radio to a whole new territory of truly multistandard, software-defined radio," said Andrew Moloney, marketing manager for receivers at RadioScape.
In parallel, RadioScape developed a single radio architecture called radiOS, designed to allow any radio, ranging from FM to DAB and Digital Radio Mondiale, to be added.
By leveraging the radiOS architecture, radio receiver manufacturers can also re-use a variety of features and applications previously developed for RadioScape's RS 300L DAB/FM module. Features include pause, rewind and record functions, local storage on an MMC card and the ability to display and use an electronic programming guide.
The radiOS architecture makes previous baseband radios, features and functions "completely transportable" to RadioScape's RS500 module, said Moloney. "Radio system vendors can use a single architecture for all product line, thus accelerating their delivery of a broad range of new multistandard radio receivers."
RadioScape is betting big on Digital Radio Mondiale. Moloney predicted that the Digital Radio Mondiale, a digital radio system for providing near-FM quality sound on broadcast bands below 30 MHz, will become a key technology for multiformat digital radio systems in 2006.
