Reddy","doi":"10.1109/WOCN.2014.6923072","DOIUrl":"https://doi.org/10.1109/WOCN.2014.6923072","url":null,"abstract":"Dual-tone multi-frequency (DTMF) is a signaling standard in telecom applications that produces two tones simultaneously for each key press. The DTMF tones are chosen such that decoding the pressed key from the received tones is very easier. The DTMF tone detection is very crucial block in several telecom based embedded systems. As the current generation embedded systems are looking for key feature of low power, the DTMF detection algorithm also must be implemented with low power schemes. The DTMF detection is done with FFT based technique but which is power consuming type and it requires more hardware. In this project the FPGA based DTMF detection with very low power and low area using Split Goertzel algorithm is implemented in VHDL. The split Goertzel algorithm itself is an area optimized solution in comparison with the FFT, but in this project we initiate efforts to further makes it low power by building lot of serialism in the design. Since DTMF based applications don't require high speed tone detection the resource sharing approach can be used. In this approach very minimal set of hardware is scheduled as inputs and outputs at appropriate clock edges, for implementing the algorithm. In the first phase of the project we implemented FFT based DTMF detection using Xilinx FFT core. The area, timing and power results is analyzed. In the second phase the split Goertzel algorithm is implemented and analysis is carried out. In the next phase the resource sharing approach is studied and suitable state machine based scheduling will be carried with limited resources to implement split Goertzel algorithm. It will be demonstrated that the novel resource sharing based approach consumes less power and can still efficiently detect the DTMF tones. To test the project at various stage DTMF tone generator module also will be implemented with digital carrier generators. Mentor Graphics Modelsim Xilinx Edition (MXE) and Xilinx ISE is used for simulation and synthesis respectively. The Xilinx Chipscope tool is used to test the FPGA inside results while the logic running on FPGA. The Xilinx Spartan 3e FPGA Family board is used in this project.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124985827","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}

Temperature, humidity and carbon dioxide levels are the most important factors for the productivity, growth, and quality of plants in agriculture. So this system periodically measures these parameters inside the fields, thus the farmers or the agriculture experts can observe the measurements from the web simultaneously. Moreover, when a critical change in one of the measurements occurs, then the farmer will be intimated via mobile text message and e-mail by an agriculture expert. With the continuous monitoring of many environmental parameters, the grower can analyze the optimal environmental conditions to achieve maximum crop productiveness, for the better productivity and to achieve remarkable energy savings.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130748957","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}

Besides several practical advantages, CDMA suffers with multiuser interference, limiting the spectral efficiency drastically. There are various optimal and suboptimal multi user detection techniques in CDMA to overcome this problem. These MUDs identify the desired users signal but the interference signal is high and there is a chance of loosing the signal. By considering these drawbacks, we propose a MUD technique using Elliptic Curve Cryptography (ECC). The main objective of this technique is to detect the desired user signal with less interference ratio. An elliptic curve based key is generated and encoded the user signals before transmission. A BPSK technique is used for modulating the signals. The decoder decodes the desired user information and neglects the undesired user information. The performance comparison shows that this technique has better performance than the existing methods.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130827937","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}

Finite Difference Time Domain (FDTD) method and transparent boundary condition (TBC) is used to analyze the dispersion property in a high-index core PCF. This method produced best result at third attenuation coordinate (1.55μm) over 1.4 μm to 1.8 μm wavelength range and found the dispersion is minimum (±0.81ps/km.nm)and ultra flattened that has better performance than conventional photonic crystal fiber. It is also shown that borosilicate glass PCF provides much better dispersion as compared to silica of the same structure, so such PCF have high potential to be used as a dispersion compensating fiber in optical window.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133365486","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 one approach the overall end-to-end throughput (OEET) improves as the number of cognitive radio relays (CRRs) increases in CRN. In this approach, the OEET increases with the number of CRRs but at the cost of increased transmission power and overheads, so simple and practical approach is proposed for the relay selection from a set of M CRRs then the channel allocation is performed with this selected cognitive radio relay (CRR). This proposed relay selection scheme uses channel conditions of the cooperative links as a metric for selecting the best cognitive radio relay. Simulation results show that the best CRR selected through the proposed approach performs better than the single CRR, in both the cases of with and without channel allocation (CA). Simulation results are compared with channel allocation (CA) scheme presented in [1]. The selected best CRR gives better performance than single CRR when combined with the channel allocation scheme, i.e., first select the best CRR with proposed relay selection approach and then perform channel allocation.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127607307","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}
