However, the size of the microstrip antenna often puts a limit to the extent to which the size of a device can be. Half-wavelength and quarter-wavelength antennas are considered as standard in many theoretical works. In some recent works some fractional wavelength antennas with electrical size reduced up to only a small fraction of wavelength have been proposed. In this work, a new approach has been presented that attempts to eliminate the convention of considering operating frequency as a limiting condition for design of microstrip antenna and provides the freedom of selecting a considerably small antenna irrespective of operating frequency. The key feature of the antenna is a Complementary Split Ring Resonator (CSRR) which is used at the ground plane. By adjusting the various dimensions of the CSRR structure resonant frequency at different frequencies can be obtained. In this way the electrical size of a stripline fed rectangular antenna is reduced up to only 12.9% of resonant wavelength.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"9 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114007049","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}

Nowadays devices like mobile, tablets, Digital TV have capability to display high resolution images for better viewing experience. Therefore the need arises to enhance the resolution of available images in real time for better perceptual quality. This paper focuses on super-resolution of shallow depth of field images which are widely used in macro, portrait or sports photography. The proposed hybrid approach first segments the low resolution image into the object of interest (foreground) and background. Subsequently, super resolve the object of interest by sparse representation and background by traditional interpolation approaches. This approach helps to reduce the overall time complexity and enhance the quality by extracting significant features from object of interest and reduce computations for shallow depth of field images. Experimentally it has been inferred that hybrid approach performs better than existing state-of-the-art super-resolution approaches in terms of time complexity.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126604680","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 the transmission data rates increase, the signal strength at the receiver side decreases due to channel loss, Inter-Symbol-Interference (ISI), crosstalk, and reflections. The Input-Output (IO) buffers are, therefore, designed with inbuilt equalization circuits to recover clock and data at the receiver. In order to verify the serial link performance, one needs to simulate the PCB/Package channels with IO buffers. Capturing BER at millions of bits, requires days and weeks of simulations using standard SPICE. To accelerate this analysis, it is important to model the transistor-level IO buffers as DSP algorithms representing the equalization. This paper presents the DSP techniques used in modeling the equalization for Analog Buffers for multi-giga-bit (Gbps) serial links.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131617030","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}

For a smart grid network, communications infrastructure/protocols and wireless networking will play an important role in achieving these objectives. The communication network designing will involves detailed analysis of the communication requirements, appropriate protocol architecture, choice of the most suitable technologies, and a resultant heterogeneous network management system. Smart grid deployment is mainly about defining the necessary standards for ICT solutions. To achieve significant advantages over traditional communication technologies, smart grid also involves its collaboration with wireless sensor networks (WSNs). Recently, WSNs can enhance various aspects of today's electric power systems that include generation, delivery, and utilization. Since communication will be through wireless channel, the security of the network/data is also to be considered. The large scale and autonomous features of a smart grid render its cyber security quite vulnerable to adversaries. This proposed manuscript will present a broader view of the smart grid networks and the various diversified fields that are integrating to create this interdisciplinary research area.

Focus of the work is to compare the performance of RPS based features with the performance of MFCC based features for non-intrusive speech quality evaluation. MFCC is a close approximation of human auditory system and used in speech quality evaluation. The use of features based on RPS captures the true dynamics of the original speech signal and existence of non-linear characteristics of human speech production system. It replaces the conventionally used power spectrum estimation (PSE) method like FFT by two dimensional DFT methods. The Gaussian Mixture Model (GMM) is used for the mapping of these features to the mean opinion score (MOS). The evaluation of these features has been done for ITU-T Supplement-23 database and the comparison of performance for both of the features has been done in terms of correlation co-efficient between the subjective MOS and the objective MOS.","PeriodicalId":318875,"journal":{"name":"2015 International Conference on Signal Processing and Communication (ICSC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133157081","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}
