The fingerprints of several ZigBee base-stations are used to construct the dictionary matrix. We propose a weighted-coefficient-approach (WCA) to determine the sensor position based on the solution of the CS problem. Numerical simulations and experiments are conducted to show that the proposed WCA outperforms the conventional CS-based approach for source localization. Numerical results demonstrate that the WCA can be used to determine the sensor position with high accuracy.","PeriodicalId":256818,"journal":{"name":"2017 40th International Conference on Telecommunications and Signal Processing (TSP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129801720","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}

The robustness in a wireless environment combined with the ease to perform the channel estimation (CE) are the reasons for the OFDM popularity. Commonly, the channel estimation(CE) is performed in frequency domain using pilot tones. It is known that the wireless communications may be affected by unknown interference from adversaries such as radio jamming (RJ), which can lead to degradation of performances. This work is focused on the RJ on OFDM modulations. We propose a new RJ strategy, called Non Uniform Power Allocation Pilot Tones Jamming (PTJ), and show, through analysis and Monte-Carlo simulations, that it presents improved performances with respect to other existing conventional RJ attack, such as barrage jamming (BJ) and PTJ, known in the open literature.","PeriodicalId":256818,"journal":{"name":"2017 40th International Conference on Telecommunications and Signal Processing (TSP)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130764082","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}

Based on real measurements, a simplified dynamic signal model of a distribution of heartbeat sounds (HS) through human body was realized. This model allows the design, realization, and verification of the adaptive system least mean squared (LMS) algorithm. This system enables to extract fetal heart rate from a sensor placed on the abdomen, where an unwanted maternal phonocardiogram (mPCG) impairs this important signal. Standard filtration methods cannot be used because phonocardiogram of fetus and mother operate on the same frequencies. The functionality of the designed system was verified by objective parameters such as Signal Noise to Ration (SNR), Sensitivity (S+), and Positive Predictive Value (PPV).","PeriodicalId":256818,"journal":{"name":"2017 40th International Conference on Telecommunications and Signal Processing (TSP)","volume":"41 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125916184","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 this paper, we present a natural extension of the multi-scale low rank model and propose its combination with a measurement operator. This modification is necessary for utilization of the model in compressed sensing perfusion MRI, where the compressed acquisition is crucial to achieve high spatial and temporal resolutions.
