—Medical professionals need a reliable prediction methodology to diagnose cancer and distinguish between the different stages in cancer. Classification is a data mining function that assigns items in a collection to target groups or classes. C4.5 classification algorithm has been applied to SEER breast cancer dataset to classify patients into either "(More)
Orthogonal Frequency Division Multiplexing (OFDM) is the digital multicarrier modulation scheme for high speed communication systems. One of the major problems in OFDM is the occurrence of high Peak to Average Power Ratio (PAPR). Due to high PAPR the signal leads to out-of-band (OBO) distortion and increase in Bit Error Rate (BER). The reduction in PAPR is(More)
We investigate the high peak power resulting from the transmission of orthogonal frequency division multiplexing (OFDM) signals through optical fiber. High peak-to-average power ratio (PAPR) which is a major drawback of OFDM can make worse the nonlinearities experienced in optical fibers. Phase modulation instead of intensity modulation is adopted to keep(More)
This paper proposes a novel scheme based on Relaxed Greedy Algorithm (RGA) to reduce Peak to Average Power Ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) systems. OFDM uses a number of independent sub carriers of different frequencies for modulation. The resultant signals have very large PAPR which can significantly impact the power power(More)
This paper presents Direction based Hazard Routing Protocol (DHRP) for disseminating information about fixed road hazards such as road blocks, tree fall, boulders on road, snow pile up, landslide, road maintenance work and other obstacles to the vehicles approaching the hazardous location. The proposed work focuses on dissemination of hazard messages on(More)
