However, this setup imposes extra difficulty to the localization of submerged targets since they are outside of the convex hull formed by the anchors. In this paper, we propose a semi-definite programming (SDP) based localization approach that is augmented by measurements obtained via onboard pressure sensors. Compared with the widely-adopted linearized least squares solution, simulations show our augmented SDP offers improved accuracy for point localization and faster convergence for tracking, under the same system configuration and environmental conditions, especially at low signal to noise ratio (SNR).","PeriodicalId":124509,"journal":{"name":"2013 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2013)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121761407","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 resolve the problem of 1553B bus message transmission performance and ensure the real-time transmission of system message, this paper proposed a new method to research the reliability and stability problem of 1553B bus using Deterministic and Stochastic Petri Nets (DSPN). We constructed a model for message transmission based on DSPN, and then derived some important performance indexes. The experimental results show that these indexes can optimize the message transmission. The average delay of messages processing on bus is 0.191434us and the average waiting time is 0.738653us.

For a given degree distribution, the expected number of cycles in randomly constructed Tanner graphs has negligible changes with the size of Tanner graphs.

Firstly, the product high-order ambiguity function (PHAF) is used to estimate the instantaneous phase and amplitude of the received Doppler signal. Then the abeam moments when tone noise sources have the closest approach to the measuring hydrophone are estimated by nonlinear weighted least-squares algorithm. Locations of tone noise sources are obtained by referring to a known acoustic source fixed on the moving object at last.

However, when several MTs send information to ground command center simultaneously, using the handoff algorithm based on RSSI will lead to HAPs with large received signal strength overload and HAPs with small received signal strength idle, putting HAPs network at risk of load imbalance and causing the phenomenon of congestion and packet loss, which thereby increases end-to-end delay and reduces packet delivery ratio. Aiming at the above problem and considering the limited energy of HAPs, a load balancing handoff algorithm based on RSSI and energy-aware in HAPs network is proposed. The simulation results obtained show that compared with the handoff algorithm based on RSSI, the proposed handoff algorithm can effectively balance network loads, reduce end-to-end delay and improve packet delivery ratio.","PeriodicalId":124509,"journal":{"name":"2013 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2013)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130788157","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, a novel spectrum sensing scheme based on energy detection is presented which enables a significant reduction in the number of samples. The sensing process involves several stages and each stage employs two thresholds that are adjusted according to the number of samples. Furthermore, an iterative algorithm is developed for obtaining the optimal number of samples at each sensing stage. As the proposed scheme requires fewer samples of signal, there will be less time for sensing and more time for data transmission which contributes to an improvement in the throughput of the CR networks. Numerical results are provided to show that the proposed sensing scheme has a clear advantage over the conventional energy detection.","PeriodicalId":124509,"journal":{"name":"2013 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2013)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126780951","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, such superior performance, especially the resolution capability is greatly restricted by the number of observed measurements. Specially, if the measurements are reduced, images with high sidelobes and lower resolution are formed. The recent developed compressed sensing (CS) as well as its application in radar imaging demonstrates that, if the sparsity constraint is cooperated in the imaging technique, high resolution imaging quality can be still achieved, even using limited measurements. In this paper, a new chirp scaling azimuth compression technique based on CS theory is proposed, which exploits the sparse property of the measurements in azimuth dimension, and the sparsity constraint is combined with the CSA to perform all the azimuth processing steps. Comparisons were performed between the proposed algorithm using data under-sampled in the azimuth dimension at different ratios and the traditional CSA using full data set at different signal-to-noise ratio (SNR). Results show that the proposed CS based algorithm has better performance than the traditional algorithm even with using low percentage of the azimuth data and also indicate that the proposed algorithm is robust with the existence of low SNR.","PeriodicalId":124509,"journal":{"name":"2013 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2013)","volume":"427 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123010121","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}
