In radio communications, the<br>bandwidth is determined by the radio frequency (RF) part,<br>antenna and application. Nowadays, the bandwidth of the radio<br>communication channel can reach hundreds of GHz, therefore,<br>pulses with a duration of few picoseconds, theoretically, can<br>be used. In the case of the optical transmission, the length of<br>the pulses, theoretically, can be below 1ps.<br>The objective of the given research is to develop software<br>framework and testbed for the exploration of pulse position<br>modulation (PPM) communication using short electrical pulses<br>with duration in the range of between 20 and 40 ns. The main<br>difference to existing work is employment of high-accuracy<br>event timer for the demodulation.<\/p>\n\n\n\n<p>In our latest article we explore the possibilities of using event timer based demodulator for achieving such feat.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"731\" height=\"354\" src=\"http:\/\/www.picoppm.org\/wp-content\/uploads\/2022\/09\/Timer_discovery_diagramm.drawio.drawio.png\" alt=\"\" class=\"wp-image-125\" srcset=\"http:\/\/www.picoppm.org\/wp-content\/uploads\/2022\/09\/Timer_discovery_diagramm.drawio.drawio.png 731w, http:\/\/www.picoppm.org\/wp-content\/uploads\/2022\/09\/Timer_discovery_diagramm.drawio.drawio-300x145.png 300w\" sizes=\"auto, (max-width: 731px) 100vw, 731px\" \/><figcaption>Fig. 1.
