However multicarrier modulation exhibits a significant sensitivity to the phase noise of the oscillator used for frequency down-conversion at the receiver. In order to give a quantitative measure of such impairment, in this paper we evalu- ate the impact of he oscillator phase noise on the ...

Phase noiseis a measure of thespectral purityof an oscillator and is a significant limiting factor affecting overall performance of microwave systems. 2. Oscillator noise is referred to asphase noisebecause, although the noise generated within the oscillator will be random in both amplitude and phase...

This letter proposes a pilot subcarrier allocation approach for orthogonal frequency division multiplexing systems, which enables construction of symbol-wise phase-noise (PN) estimates with high efficiency and low overhead in a non-iterative manner. The complexity and performance of the overall PN supp...
