Abstract
U radu je razvijen Matlab model UWB impulsnog radio sustava koji za akviziciju signala na prijamnoj strani koristi sažimajuće očitavanje. Model prijamnika razvijen je za AWGN kanal. Za rekonstrukciju Kroneckerovog niza impulsa korišten je koherentni detektor. Prijamnik je uhodan na različitim valnim oblicima pulseva te modulacijama. Za ilustraciju rada prijamnika korišten je UWB puls dobiven kao četvrta derivacija Gaussove funkcije te amplitudna modulacija impulsa. Akvizicija je izvedena Gaussovom mjernom matricom, dok je rekonstrukcija signala izvedena optimizacijom nad stošcem drugog reda koji je definiran šumom u kanalu. Rekonstrukcija je izvedena korištenjem alata L1-MAGIC i CoSaMP, pri čemu se L1-MAGIC pokazao robusnijim.
Abstract (english)
In this work, Matlab model of the UWB impulse radio system using compressive sensing acquisition at the receiver is developed. The receiver is designed for AWGN channel. For the reconstruction of Kronecker’s impulses, coherent detector is used. The receiver is tested for various pulse waveforms and modulations. To illustrate its features, the fourth derivative of the Gauss function and amplitude shift keying are used. The acquisition is performed using the Gauss random matrix, and the reconstruction is worked out by the second-order cone programming. For the optimization, tools L1-MAGIC and CoSaMP are used. However, the L1-MAGIC reconstruction is more robust.
