Conventional software radios take advantage of vastly improved analog to digital converters (ADC’s) and digital signal processing (DSP) hardware. Our approach, which we refer to as virtual radios, also depends upon high performance ADC’s. However, rather than use DSP’s, we have chosen to ride the curve of rapidly improving workstation hardware. We use wideband digitization and then perform all of the digital signal processing in user space on a general purpose workstation. This approach allows… CONTINUE READING
