In this paper the authors evaluated the compressive sensing (CS) as possible technique for speeding up the acquisition time of this kind of application. In effect the CS approach could reduce the number of acquisition points, and then the measurement time by using only a random pattern of the antennas positions. The authors found that the data reconstruction loses quality even with a reduction of 25 % of the number of acquisitions, but the features of the targets still visible. With a reduction of 50 % the SNR decrease sensibly and most of the targets are not detectable. Such a time reduction results rather marginal in most practical cases.","PeriodicalId":383018,"journal":{"name":"2018 41st International Conference on Telecommunications and Signal Processing (TSP)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122525636","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}

By appending one zero to the transmitted symbol, our technique provides a perfect reconstruction of the original signal at the receiver (in the absence of noise), after a simple procedure by using exclusively the DCT3e. We propose a matrix formulation which allows the diagonalization of the channel via the DCT3e; moreover, the one-tap per subcarrier coefficients for the reconstruction are also obtained by means of the DCT3e. We provide theoretical results and present simulations, using ITU-T's pedestrian channel B, which show the good behaviour of the proposed reconstruction algorithm.","PeriodicalId":383018,"journal":{"name":"2018 41st International Conference on Telecommunications and Signal Processing (TSP)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122773811","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}

In order to process this huge amount of data and the large number of potential temporal evolutions, multitemporal analysis techniques need to be developed. In this paper, we propose a simple, unsupervised, yet effective technique towards the retrieval of spatio-temporal patterns from satellite image time series (SITS). Following a query-by-example procedure, the proposed method is able to extract patterns that are similar to a given query under two use case scenarios, i.e., short and long SITS, respectively.

In this work it is shown that this idea is not exactly true and it considerably underestimates the overall NF. To verify this claim, Z-model of the lossy network is added before the LNA and the overall noise figure is recalculated for some commonly used LNA topologies. It is shown that in common gate LNA and common source LNA with resistive feedback the accepted equation underestimates the overall NF by 1.3 dB for an insertion loss of 2 dB. In common source with resistive matching and in common source with inductive degeneration the exact value of NF is almost the same as the value obtained from the accepted equation.","PeriodicalId":383018,"journal":{"name":"2018 41st International Conference on Telecommunications and Signal Processing (TSP)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126990799","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}

After encoding the bits in a physical property of a molecular wave, the transmitter releases the molecules into the fluid environment where they diffuse randomly according to the laws of Brownian motion. For consequent bit transmission scenarios, the random nature of the channel causes inter-symbol interference (ISI) for the system, which affects communication performance and poses limits on the range and the bit rate of the communication. Due to facing different amounts of ISI for different bit sequences, each sequence combination should be evaluated when deriving the theoretical bit error rate of an MCvD system. Emphasizing the fact that some bit sequences produce considerably more bit errors than others, this paper aims to reduce the number of evaluations required to derive theoretical approximate bit error rates while preserving sufficient precision.","PeriodicalId":383018,"journal":{"name":"2018 41st International Conference on Telecommunications and Signal Processing (TSP)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133490665","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}
