A PAPR Reduction Scheme using Modified Weighted OFDM

Seema Kushwah, Satish Kumar, Sandeep Singh Bhadoriya

OFDM is successfully used in many wireless digital communication system over multipath channels. One of the principle disadvantages of OFDM is the occurrence of high PAPR. OFDM signals are very sensitive to nonlinear effects due to the high PAPR, which leads to the power inefficiency in the RF secti...

Diagnosis of Diabetes Mellitus Using PCA, Neural Network and Cultural Algorithm

Anjali Khandegar, Khushbu Shah Pawar

Diabetes Mellitus (DM) is a chronic metabolic disorder characterized by the hyperglycaemia with the disturbances of body metabolism resulting from the defects in insulin secretion, insulin action, or both. The chronic hyperglycaemia of diabetes is associated with the long term damage, dysfunction an...
