However, a number of the multipath interferences present in the reference signal in most cases. The existence of the multipath interferences can increase the false alarm rate and raise the detection threshold giving rise to lower detection rate. Therefore, the direct path wave should be purified. This paper proposes a direct path wave purification algorithm based on the normalized least mean square (NLMS) algorithm. This algorithm can attenuate the multipath interferences of the direct path wave, which results in the lower false alarm rate and lower detection threshold. This algorithm is validated by the experimental results.","PeriodicalId":124509,"journal":{"name":"2013 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2013)","volume":"30 2 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":"123087268","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}

This method is called Acoustical Transfer Function Ratio based on Statistical Model (ATFR-SM). In our algorithm, the noise reduction method based on the statistical model is adopted to reduce the effect of noise on Acoustical Transfer Function (ATF). In the ATF method, the Power Spectral Density (PSD) is whitened to reduce the effect of reverberations. Voice Activity Detection (VAD) is used to distinguish the speech period from the noise period, and the TDE is performed in the speech period to improve the estimation accuracy. The results of performance evaluation show that, in both the noisy and reverberant conditions, the lower Percentage of Abnormal Points (PAP) and lower Root Mean Square Error (RMSE) can be achieved by the proposed method than the reference methods.","PeriodicalId":124509,"journal":{"name":"2013 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2013)","volume":"26 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":"123568308","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}

To implement debugging of embedded processor, Debug Support Unit and Debug Handle Unit is designed. The method fits for mainstream SoCs. It includes various debug functions and few limitations of debug interface, which is also very efficient.

In this paper, we design multiple orthogonal waveforms by applying the multiple subcarrier technique in digital communications to commonly-used chirp radar waveform with large time-bandwidth product and constant modulus, so that the orthogonality of subcarriers within a common frequency band and good properties of chirp waveform are sufficiently exploited. The detailed modulation and demodulation methods are presented and the application potentials of the new waveform in MIMO-SAR are investigated. The proposed waveform diversity design method has the advantages of implementation simplicity and easy integration with the conventional SAR processor. Semi-physical simulation with an Agilent arbitrary waveform generator (AWG) and a high-speed oscilloscope (OSC) verifies the scheme. The performance is also evaluated by theoretical analysis and simulation results.","PeriodicalId":124509,"journal":{"name":"2013 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2013)","volume":"107 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":"125902243","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}

Thus, the online detection of the oil tank storage capacity is studied to handle this issue. By analyzing the tank displacement in longitudinal tilt and lateral deflection, the oil storage capacity calculation model in the tank displacement state is given. The model of the displacement parameter identification is established using Least-squares Method, their parameters are obtained using Monte Carlo algorithm. The tank capacity table is calibrated using the filtered data, and the model has been further optimized. The simulation results show that the proposed method is practical and reliable, and could improve the measurement accuracy of the oil reserved in the tank displacement state.

The paper proposes a method which combines with multi-scale wavelet transform modulus maxima and GVF snake algorithm to extract the contour of cervical lymph node. Firstly, the proposed method obtains the initial contour of the ultrasound image with using an algorithm of edge detection called wavelet transform modulus maxima, and then using GVF snake model can extract the accurate contour of the image. Experiments show that the method overcomes the disadvantages of the wavelet analysis getting the discontinuous edge; it is better in noise immunity and anti-artifact interference compared with the traditional GVF snake model. In addition, the initial contour is close to the real edge of the given image, thus it reduces the iteration number of gradient vector flow (GVF) field and improves the convergence speed of the contour.","PeriodicalId":124509,"journal":{"name":"2013 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2013)","volume":"111 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":"129659323","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 target MR image is formulated as a linear combination of a motion compensated reference image and a difference image. Both the global and the local deformations are estimated to enhance the sparsity of the difference image. The global motion is estimated by affine transformation. The local motion is described by hierarchical B-spline refinement, and non-uniform control points at each level are used to speed up the registration. In addition, we replace the l1 norm term with a weighted l1 norm to further improve reconstruction quality. The proposed method is applied to a numerical phantom data set and an in-vivo data set.
