Recently, a family of quadratic APN functions was demonstrated by Bracken et al. to exist over with k even and 3 ∤ k. This family of APN functions was firstly proposed by Budaghyan et al. and they exist provided the existence of a quadratic polynomial of the type with no zeros in . Bracken et al. constructed...
In this paper, a numerical investigation on the nonlinear distortion of OFDM (Orthogonal Frequency Division Multiplexed) signals caused by RSOA (Reflective Semiconductor Optical Amplifier) as an intensity modulator in OFDM-PON system is undertaken. Based on curve fitting approach a fourth order polynomial is, for the first time, used to present the nonlinear gain of RSOA. The expression of in-band...
