Abstract

This paper explains the mechanisms that lead to a degradation of an OFDM signal because of the phase noise of the RF oscillators. An approach for easy calculation of SNR, independent of carrier numbers, will be given. This SNR approach uses a plot of the phase noise power density for the calculation. The theoretical results lead to an improved synthesizer concept. Values of SNR and BER will be given for the new synthesizer concept. >
射频振荡器对ofdm信号的影响
本文解释了由于射频振荡器的相位噪声导致OFDM信号退化的机制。本文将给出一种简便的、不受载波数影响的信噪比计算方法。这种信噪比方法使用相位噪声功率密度图进行计算。理论结果导致了一个改进的合成器概念。给出了新合成器概念的信噪比和误码率。>
