PPT-On phase noise and it effect in OFDM communication system

School of Electrical Engineering KTH To provide an overview of oscillor phase noise and its influence on OFDM systems Objective Over view of the phase noise phenomenon Ideal oscillator delivers a pure sinusoid. Husheng Li. The University of Tennessee. White Noise. When the noise spectrum is flat, we call it white noise.. The spectral density is given by. Filtered (Colored) Noise. When passed through a LTI filter with transfer function H(f), we have . There are different “flavors” of OFDM according what we put in the Prefix:. data. P. data. P. data. P. time. Prefix.
