Approximation of the average power variation for Geometric adding signal approach of PAPR reduction in context of OFDM signals
Désiré Guel, Jacques PalicotOne of the major drawbacks of adding signal techniques of reducing peak to average power ratio (PAPR) is the variation of the average power of the transmit signal that undoubtedly degrades the performance of transmission. In this paper, assuming that the baseband OFDM signal is characterized as...

Frequency based asymptotic distribution of the PAPR for geometric adding signal approach in OFDM signals context
Guel, D. and Palicot, J. and Bellanger, J.-J.The distribution of the peak-to-average power ratio (PAPR) for Geometric method [1] of PAPR reduction in orthogonal frequency-division multiplexing (OFDM) signals is evaluated in order to analyse the influence of the carrier frequency of adding signal on the PAPR reduction. Assuming that the...

Numerical study of cooling water via an evaporatively cooled immersed porous tube
D. BATHIEBOWe present a numerical study of the cooling of a volume of water through the wall of a cylindrical terracotta tube, the pores of which are saturated with water. The internal surface of the wall carries a water film which evaporates by forced convection of hot and dry air. Taking into account the...

Provitamin A carotenoid content of dried fermented cassava flour: The effect of palm oil addition during processing
Inocent Gouado , Adelaide Demasse Mawamba , Ruphine Solange Meyimgo Ouambo , Issa Touridomon Some and Tchouanguep Mbiapo FélicitéVitamin A deficiency is a public health problem in developing countries. Cassava is a major staple food for most Africans. Most often, it is processed into dried fermented cassava (commonly called gari) to limit post harvest losses. The white or yellow type of gari can be obtained without or...
