In this paper we will discuss the influence of utilizing the selective mapping technique for PAPR reduction in SC-FDMA systems for various modulation schemes. Actually, Single carrier frequency division multiple access (SC-FDMA) has not only utilized the single carrier modulation, and has the most features of OFDMA, but also, it has an outstanding feature.(More)
This research introduces the hybrid Multilayer feed forward Neural Network (NN) and the Maximum Likelihood (ML) technique into the problem of estimating a single component chirp signal parameters. The unknown parameters needed to be estimated are the chirp-rate, and the frequency parameters. NN was trained with several thousands noisy chirp signals as the(More)
