Hybrid PAPR Reduction Scheme for Universal Filter Multi-Carrier Modulation in Next Generation Wireless Systems: Crimson Publishers

Hybrid PAPR Reduction Scheme for Universal Filter Multi-Carrier Modulation in Next Generation Wireless Systems by Himanshu Monga in Crimson Publishers: Peer Reviewed Material Science Journals

Universal filter multi carrier (UFMC) is one of the promising multi carrier modulation techniques for next generation wireless communication systems. UFMC seems to be most attractive because it provides better sub carrier separation like FBMC (Filer Bank Multi Carrier) and less complexity like OFDM (Orthogonal Frequency Division Multiplexing). But this technique suffers from limitation of higher Peak to Average Power Ratio (PAPR). In this paper a Hybrid PAPR reduction technique SC- UFMC have been proposed using SLM (Selective Mapping) and Clipping. The performance of proposed technique is evaluated for various design parameters including filter length, FFT size and Bits per sub carrier. The simulation results show that hybrid technique provides better PAPR reduction as compared with conventional SLM and clipping techniques.

Research & Development in Material Science(RDMS) ISSN: 2576-8840

Image
Research & Development in Material Science provides an international media for the publication of experimental and theoretical studies related to the load-bearing capacity of materials as influenced by their basic properties, processing history, microstructure and operating environment. RDMS is a relatively new scientific field which involves studying materials through the materials paradigm (synthesis, structure, properties and performance). It incorporates elements of physics and chemistry and is at the forefront of nanoscience and nanotechnology research. RDMS focuses on scientific and/or engineering factors affecting the relationships of materials, particularly appropriate for research and development in material science. RDMS is primarily interested in those contributions which bring new insights. Papers will be selected on the basis of the importance of the new knowledge they provide. The main theme of this journal is to spread the advanced research technologies in Mat...
