The optimized version of the indirect time-domain method based on a numerical electromagnetic code (NEC) used in combination with fast Fourier transform (FFT) is presented. One of the most serious limitations of the indirect time domain methods when compared to direct time-domain methods, relative inefficiency, is tackled by applying an optimization during transfer function calculation. The optimization...
This paper presents a simple iterative method for reconstruction signal affected by nonlinear distortion in OFDM transmitter and AWGN channel. The proposed method is based on iterative estimation of the samples affected by clipping. Position of the samples that are affected with clipping are estimated by comparing the magnitude of the inverse Fourier transform of the estimated signal in frequency...
