Block SLM Scheme for Efficient PAPR Reduction in OFDM Systems
Abstract: AbstractOrthogonal frequency division multiplexing (OFDM) is an attractive technique due to its high-speed data transmission and robustness for time-selective channels. However, the major drawback of OFDM system is high peak-to-average power ratio (PAPR). In this paper, two PAPR reduction schemes have been introduced; one is conventional selected mapping (SLM) scheme and a new proposed block selected mapping (BSLM) scheme to obtain PAPR reduction performance in OFDM system. In the proposed …

Partial View-Based Object Recognition using Leave-one-out Approach with Classification and Regression Trees
Abstract: Object recognition from image is an intriguing task in computer vision. It is simple for human being but complex for machine because of complex background, lightening, different viewing angle, size etc. So, a typically automatic and robust system is required to recognize object. In this paper, a content-based object recognition system using only one view of the object: top view, front view, back view, side view, and also using combination …

Reconstruction Techniques for Super Resolution Using Low Resolution Images
Abstract: The aim of Super Resolution (SR) reconstruction is to restore High Resolution (HR) image using information obtained from many degraded and aliased Low Resolution (LR) images. SR is signal processing for bandwidth expansion beyond the pass band of the imaging hardware system by using spatio-temporal information available from LR images. Over last three-decade various researchers contributed in the field of SR, but all are intuitive SR mechanisms. This paper employs …

Treatment Planning Techniques in External Beam Photon Radiation Therapy
Abstract: Volumetric modulated radiation therapy (VMAT) is a modern treatment technique in radiation therapy, and it delivers conformal radiation dose to the tumor while minimizing dose to the normal tissues. The beam delivery is done in the form of one or multiple arcs, with gantry rotating around the treatment isocenter. A number of literature suggests that VMAT could be an attractive option to treat prostate cancer. However, there is no consensus …
