Abstract
Tato bakalářská práce se zabývá kódováním na fyzické vrstvě sítí. Cílem je seznámení se s touto problematikou, která bere v potaz chování elektromagnetických vln ve stejném fyzikálním prostoru a pracuje s tím. Výsledkem je lepší propustsnost a chování systému. Součástí práce je implementace a simulace chybovosti v topologii Two-way relay channel, která je speciálním případem tak zvané "motýlí" topologie. Dále je zkoumána topologie se třemi zdrojovými uzly, které používají BPSK modulaci, a jedním přeposílacím uzlem se zaměřením na HNC mapu a H-konstelaci na tomto uzlu. Krátce jsou nastíněny nápady, jak určit kvalitu HNC mapy pro danou parametrizace kanálu.
This bachelor thesis deals with Wireless Physical Layer Network coding. The aim is to get acquainted with this issue, which takes into account the behavior of electromagnetic waves in the same physical space and works with it. By using this approach, we can achieve better system throughput and performance. Next part of the study is the implementation and simulation of error rate in Two-way relay channel, which is a special case of so-called "butterfly" network. Topology with three source nodes that use BPSK modulation, and one relay node with focus on the HNC map and the H-constellation at the relay node is examined. Briefly, a few techniques are summarized on how to determine the quality of the HNC map for a given channel parameterization.
