Advanced Software Defined Radio
Time-frequency representations are used to analyze time-varying signals with respect to their spectral contents over time. Apart from the commonly used short-time Fourier transform, advanced …
The traditional radio receiver uses analog processing, i.e. analog mixers, filters and amplifiers to convert the incoming RF analog signal from the antenna to baseband, …
The demodulation of single-sideband (SSB) signals requires special attention, because simple mixing leads to superposition of the upper and lower sidebands at audio frequencies. The …
This an excerpt of my more extensive paper on Xilinx’s Zynq System-on-Chip for Software Defined Radio processing from 2018: “The Xilinx Zynq: A Modern System …
Digitizing Signals and Discretization The heart of a direct conversion receiver is the analog-to-digital converter (A/D converter or ADC), that samples analog signal in order …
With the advent of digital technology, analog circuits in radio transceivers have been widely replaced by digital signal processing. This is because digital signal processing …
