Orthogonal Frequency Division Multiplexing (OFDM) is one of the Strong candidate for Transmission of high data rate due to Multicarrier Modulation. One of the challenging Issue of OFDM is its high Peak to Average Power Ratio (PAPR or PAR). This Paper discusses different PAPR Reduction techniques in OFDM. The Classical Clipping, Selective Mapping, Tone reservation and Partial Transmit sequence T...
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract One of the emerging technologies in the field of communications is wireless technology. It provides efficient data transmission and a growing concept for 4G and 5G communications. The concept of OFDM system states that it is a form of multi-carrier...
Transradial (TR) coronary intervention is associated with fewer access-site-related bleeding complications and is independently associated with a lower risk of mortality following PCI compared to procedures undertaken through the femoral route. However, recent studies that have undertaken imaging of the radial artery through the use of IVUS and OCT, as well as histological studies, suggest that...
In the previous chapter, to get high data rate transmission, High Throughput techniques were analyzed for OFDM-MIMO System. OFDMMIMO systems based on OFDM symbols suffer from the problem of inherent Peak to Average Power Ratio (PAPR). The peak power of a multi carrier OFDM signal is a critical design factor for band limited communication systems, and it is necessary to reduce it as much as poss...
نقش استرس در شروع و تشدید اختلالات روانی، سال هاست که هدف بسیاری از تحقیقات بوده است. از این رو محور چهار dsm-iv-tr به این نوع حوادث، اختصاص داده شده است. با این وجود، مسائل ذکر شده در این محور، اولاً بسیار کلی است، ثانیاً ممکن است قابل تعمیم به تمام فرهن گها نباشد. در این تحقیق به روش نمونه گیری تصادفی ساده، پرسش نامه ادراک حوادث استرس آور در میان گروهی از دانشجویان دانشگاه های شهرستان اهواز، تو...

This paper addresses the issue of providing QoS services for Optical Burst Switching (OBS) systems. We propose a Linear Predictive Filter (LPF)-based Forward Resource Reservation method to reduce the burst delay at edge routers. An excessive reservation method is utilized to increase the successful forward reservation probability and to improve the delay reduction performance. We also discuss a...
