| Popis: | In orthogonal frequency-division multiplexing (OFDM) transmission schemes, nonlinear distortion from high power amplifiers and phase noise due to oscillator instability are potentially serious problems, especially in millimeter-wave transmission systems. In this paper, we investigate and compare the combined effects on uncoded and coded OFDM signals of amplifier nonlinearity and phase noise from silicon-based devices. An analytical parametric formulation of system performance is presented. The theoretical results were in complete agreement with the computer simulation results. Total degradation was greatly reduced by applying a suppression scheme to compensate for the constant phase rotation in coded OFDM systems. In addition, the total coding gain defined for systems with different high-level M-QAM modulation was shown to increase with M. |
