Sensing Engine

Short testbed description

The imec sensing enigne is a prototype implementation of a sensing engine for mobile communication devices. The prototype consists of two main blocks: an analog RF front-end including analog to digital conversion and a DIgital Front-end For Sensing (DIFFS). For permanent deployment in the w-iLab.t testbed a WARP board is selected as analog RF front-end, covering the 2.4 and 5 GHz ISM bands. An in house developed flexibele SCAlable raDIO (SCALDIO) is also tested in a lab environment, covering an RF input range from 0.1 up to 6 GHz and a channel bandwidth up to 40 MHz. The digital front-end is an ASIP specifically designed for sensing operations, signal conditioning and synchronization. The chip contains a flexible filter block, including re-sampling and a SIMD core, extended with multiple accelerator cores. Multiple sensing algorithms are implemented on the system, ranging from straight-forward energy detection schemes, over more complex feature detection (for e.g. DVB-T) to multiband energy detection after FFT leakage removal for OFDMA LTE signals.

Access information

The imec sensing engine is available in the Ghent island CREW (w-iLab.t testbed).
