Predominantly speech enhancement can be categorized as echo cancellation and noise reduction. Several techniques were introduced to reduce various kinds of background noise and echo; some frequency techniques are based on spectral subtraction. In any mobile communication system (uplink or downlink) the corrupted speech will pass through a cascade or parallel network of noise reduction and echo cancellation modules. In this paper we describe a method to address the efficiency issues in the parallel network of noise reduction and echo cancellation modules by introducing a correction module so as to achieve performance as close as possible to the cascaded approach.","PeriodicalId":276158,"journal":{"name":"2015 International Conference on Applied and Theoretical Computing and Communication Technology (iCATccT)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124081431","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}

Analyzing all those factors and identifying the action is termed as activity recognition. In this paper, we present an approach of activity recognition with the help of context. Context can be termed as the relationship between the objects performing the activity. Activity recognition is performed based on motion identification and context information. We use Principle Component Analysis along with the low level features to perform feature extraction and then Support vector machine as a classifier which classifies the action into a class with label. Thus by performing a high level of feature extraction using context and by supervised training, we perform activity recognition and try to improve the recognition accuracy of the system.","PeriodicalId":276158,"journal":{"name":"2015 International Conference on Applied and Theoretical Computing and Communication Technology (iCATccT)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122445281","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}

Carrier Ag-gregation(CA) is an important technology for LTE-A providing enhancements to peak data rates, both uplink and downlink, allowing the User Equipment(UE) to receive data on more than one LTE carrier. This increased complexity is expected to affect the UE current consumption. As LTE is restricted with packet-switched services only, the 3G native circuit-switched (CS) voice mechanisms are used in LTE to support voice calls and SMS. For this purpose, the network operator may consider Circuit-switched fallback(CSFB) or IP-Multimedia Subsystems(IMS) as alternatives, for concerned voice quality, call continuity and reliable SMS delivery in deployed LTE networks. In this paper, the performance of UE under CA(10+10 MHz) is analyzed for maximizing data throughput and also describes how the CA affects UE current consumption measurements with different traffic profiles. As a part of Voice over LTE(VoLTE), this paper evaluates the performance of UE under CSFB with its effect on peak data rates and reliability on IMS for deploying voice and SMS services.","PeriodicalId":276158,"journal":{"name":"2015 International Conference on Applied and Theoretical Computing and Communication Technology (iCATccT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128681789","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}

As a consequence, harmonic contamination in power system signals is a matter of major anxiety to electrical engineers. Fast Fourier Transform (FFT) has been adopted as an analytical tool for signal processing purpose. Single phase voltage signal is chosen from a three phase supply sent to motor. Here, power analyzer interfaced with laptop is an arrangement used as data acquisition unit. Obtained wave data of single phase voltage signal is processed through the FFT program in MATLAB. Then, simulation of the voltage signal procured from data acquisition unit is designed in SIMULINK. After that, the simulated signal is filtered by Butterworth filter, Bessel filter and Chebyshev 1 filter to diminish Total Harmonic Distortion (THD) from the output after filtration.

The curvelet transform show evidence of improved multiscale directional capability, and a greater ability to localize distributed discontinuities such as edges along curves as compared to traditional multiscale transform such as wavelet transform. Hence, we transform original face images to frequency domain using curvelet transform. Noise and illumination invariant features are extracted from approximate sub-band using complete robust local binary pattern, which forms feature descriptor of facial expression. The proposed technique is assessed based on facial expression recognition carried out using a benchmark database such as JAFFE. Recognition of facial expression is achieved using a chi-square distance measure with a nearest neighbour classifier.

The precise discovery of fragments in the face image improves the confinement of the outstanding patches on face images. Some methods uses a special framework for expression identification by the use of appearance related features of important face patches. A few noticeable face patches which are alive for each expression classes are extracted considering the location of fragments in the face image. Then further process these alive patches in order to obtain the patches which are discriminant and contain features for grouping of each pair of expressions. Thus it selects different facial patches as important for each pairs of expression classes. Then use these features for performing one against one categorization method.
