'An introduction to Software Defined Radios' by
<a
href="https://twitter.com/furtado_jaden"
target="_blank"
rel="noreferrer"
>Jaden Furtado</a
>
<br />
<br />
<p>
This is to serve as a gentle introduction to the dark arts of wireless communication. People think of radios as a thing of the past, unaware of the potential that remains to be unlocked. While many are familiar with software, and some are with hardware, the wireless spectrum remains a curiosity to the masses. I'll show the basics of signal processing using Radios, along with demonstrations and applications of this technology.

Dekho is a very simple, bare bones and open source Video on Demand server which we built to understand how video streaming works at a fundamental level. The talk will consist of -
