This page gives an introduction to time-difference-of-arrrival (TDOA) based localization of transmitters and presents a simple practical system using three RTL-SDRs to localize signals in …
The Panoradio is a tech-demo for modern software defined radio (SDR), that shows what is possible with today’s technology in AD conversion, signal processing and …
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 …
Time delay analysis finds the delay (also called the “lag”) between two signals, that are shifted in time. It is the most important part of …
This article describes how to setup a low-cost TDOA system based on RTL-SDR + Raspberrry PI receivers and how to connect them via ethernet. Requirements …
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 …
