Kommunikatsioonimudel

>lõppunkti saaväljund informatsioon m' 2. Kommunikatsioonisüsteemi ülesanne • mõistlik kasutamine/koormamine • liidestus(kokku ühendamine. Ntx: võrk+võrk, arvuti+võrk) • Signaalide genereerimine(edastamine)(signaalide ühest süsteemist teise üleviimine) • Sünkroniseerimine [andmeedastuse algust(saatja) ja lõppu(vastuvõtjat)] • Andmeside haldamine • Vigade avastamine ja parandamine(näiteks side mürarikkas keskkonnas) • Voojuhtimine (vastuvõtja saab pakette vastu võtta kindla kiirusega->on vaja kontrollida andmeedastuse voogu) • Adresseerimine • Marsruutimine (vaja leida tee võrguserverini, pakettide suunamine) • Taastumine(vigastest olukordadest).

ARQ procedure is illustrated:  HARQ tööpõhimõte lühidalt: Soft Combining is an error correction technique in which the bad packets are not discarded but stored in a buffer. The basic idea is that 2 or more packets received with insufficient information can be combined together in such a way that total signal can be decoded. HARQ procedure is as follows 18. Miks on oluline CQI (Channel Quality Index) raporteerimine kiires andmeside ühenduses Meil on vajalik teada levikanali kvaliteeti, et paremini hinnata millistes tingimustes mobiil paikneb. CQI stands for Channel Quality Indicator. As the name implies, it is an indicator carrying the information on how good/bad the communication channel quality is. This CQI is for HSDPA. (LTE also has CQI for its own purpose). In LTE, there are 15 different CQI values randing from 1 to 15 and mapping

1 System development • Modelling in early system development stage corrects design errors before construction. • Beneficial modelling reasons (– Insight: in the design and operation of a system – Completeness: detection of missing parts for simulation and a better understanding of the system requirements – Correctness: errors and flaws are usually detected, problematic scenarios can be reproduced, systematic error investigation) 2 Introduction CPN • CPN is a graphical language for concurrent system design and analysis and also general-purpose modelling environment and also applicable for industrial projects and high level programming. • Petri nets provide(– graphical notation– modelling concurrency, communication, synchronisation) • CPN application domains that are typical(– communication protocols, data networks, distributed algorithms) • Broader CPN applica
