Signal processing of this atmospheric radar is necessary to measure the height profile of wind vector by detecting the Doppler shift of echoes and signal to noise ratio (SNR). The L-band wind profiler is used for conducting research in the lower atmosphere. These radars achieve better range resolution with maximum average power (height coverage). The signals, which are processed in the present work has been obtained from the LAWP at National Atmospheric Research Laboratory (NARL), Gadanki, India. SNR computation is an important parameter in signal processing. This paper discusses improvement of SNR using Empirical Mode Decomposition (EMD) for LAWP signals. SNR for this data is computed de-noised signals and EMD de-noised signals are compared with the Wavelets de-noised signals. Results shows that there is an improvement in SNR after de-noising using EMD technique for LAWP signals.","PeriodicalId":352568,"journal":{"name":"2015 International Conference on Microwave, Optical and Communication Engineering (ICMOCE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117065682","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}

Although there are many techniques like Global histogram equalization (GHE), Local histogram equalization (LHE) and other singular value based enhancement techniques, these methods are not robust as it fails to enhance very poor contrast images. By using Quaternionic Wavelet Transform the quality of the image is better enhanced compared to other wavelet transforms. QWT provides very good shift invariance and directionality than DWT. In addition to that the proposed technique maintains the brightness of the image and preserves the edges of the image with relatively fewer artifacts.","PeriodicalId":352568,"journal":{"name":"2015 International Conference on Microwave, Optical and Communication Engineering (ICMOCE)","volume":"293 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125607817","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}

A ZigBee Wireless Network is deployed at the location of interest, i.e. the open cast mine, with the ZigBee Network Coordinator attached to a Single Board Computer (SBC) which is placed at a remote place where it has uninterrupted Internet access either via LAN, Wi-Fi or Cellular Network (GPRS). The location of SBC is chosen such that the region devoid of cellular network falls within the ZigBee Coordinator's range. Other ZigBee nodes are attached to the vehicle's Tracking Equipment as ZigBee Routers. Whenever a vehicle's tracking equipment fails to make a GPRS connection, it sends its location via the ZigBee network to the coordinator which acts as a gateway and uploads the received location data to the tracking server. ZigBee Network Watchdog Timer are configured such as to allow automatic rejoining of ZigBee nodes when vehicles leave and enter the ZigBee Network Range.

The DN (digital number) values of each pixel of LISS-IV satellite image were converted into their top of atmospheric (TOA) reflectance values. The measurement of SPAD values were carried out at the same time of satellite passes over the study area. Two band algorithms was developed using cubic polynomial regression analysis between spectral coefficients and SPAD values. The performance of the two band algorithm was evaluated by using statistical performance indices like %Bias, root mean squared error (RMSE) and Nash-Sutcliffe efficiency (NSE).

Paging and location update techniques work together with to decide in searching of the user on the arrival of a call. Here a profile based paging algorithm is proposed in terms of paging success rate and bandwidth conservation comparing with various other paging algorithms. This work is validated by taking a novel data to profile the users and simulated the algorithm with actual user data.
