The OFDM modulation divides the total frequency band into several narrow band sub-channels, so that the system gets more immune to extremely hostile multipath channels. The conventional OFDM uses Fast Fourier Transform (FFT) to provide orthogonality between sub-channels, but Wavelet Packet Transform (WPT) is also proposed by different authors as an alternative orthogonalization method in recent years. In this paper, after comparing structures and features of FFT-OFDM and WPT-OFDM, we present their BER performance simulated by MATLAB over 6 tap Rural Area (RA6) channel which is defined by the European Telecommunications Standards Institute (ETSI) for Long Term Evolution transmission systems in 3GPP standard. In order to achieve deeper insight into WPT-OFDM performance, Haar, Daubechies5, Symlet5 and Coiflet4 are used as wavelet families in the simulations. At the receiver side, we use frequency domain equalizer (FEQ) for FFT-OFDM and overlap FEQ equalizer for WPT-OFDM to mitigate the fading effects of multipath channel on the received signals. Simulation results show that the performance of OFDM will be improved by using WPT, and since it does not need to use (Cyclic Prefix) CP in WPT-OFDM scheme, this method is more efficient from power and bandwidth points of view with respect to the commonly used FFT-OFDM.","PeriodicalId":313846,"journal":{"name":"2018 International Symposium on Networks, Computers and Communications (ISNCC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124923534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, depending on a stale/invalid route to recover from a broken link could increase the delay to recover from the broken link and degrade the network performance. In this paper, we propose a new MAC protocol (RIVC-MB) to enhance communication reliability in the multipath multichannel routing protocol. The reliability of transmitting/re-routing the data packet in multipath multichannel routing protocol is improved by providing early route invalidity detection and early switchover. Waiting time to access the medium is also improved, when a node is attempting to access a busy medium, by re-routing the data packet via the alternative route. The RIVC-MB protocol uses the cross-layer interaction between MAC and routing protocols to achieve these goals. The proposed protocol is implemented and extensively evaluated using the NS-2 simulator. Simulation results show that the new proposed protocol reduces the end-to-end delay, and reduces both the number of route error control packets and the number of dropped data packets in the routing layer. It also reduces the collision rate in the MAC layer in a dense network.","PeriodicalId":313846,"journal":{"name":"2018 International Symposium on Networks, Computers and Communications (ISNCC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124161514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among several institutions across Europe, Budapest University of Technology and Economics is also taking part in the propagation experiment. The measurement site is located at the university, continuously recording the unmodulated carrier levels of 39.402 GHz and 19.701 GHz along with the main meteorological parameters. The most important phenomenon that causes attenuation is the rain, considering the millimetre wave propagation. Rain intensity is usually measured by different kind of weather sensors, like tipping-bucket, drop-counter type rain gauges or disdrometers. Nevertheless, a point rainfall rate measurement e.g. at the location of the terrestrial endpoint of the radio link usually not correctly represents the rain distribution along the radio path, especially in case of long terrestrial or satellite connections. This paper evaluates the relationship between rain attenuation and rainfall intensity by using the experimental data of Ka/Q band. We extract the rain intensity information by using the measured attenuation on the radio path. For this purpose we process both the Ka and Q-band beacon signals that are transmitted by the Alphasat Aldo Paraboni payload. The dual-frequency approach allows the comparison of the results that may lead to a more accurate attenuation to rain intensity calculation method in the future.","PeriodicalId":313846,"journal":{"name":"2018 International Symposium on Networks, Computers and Communications (ISNCC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133707326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
