In this paper we present a comparative study in order to specify the influence of equalization enhanced phase noise (EEPN) for preand post-compensation of chromatic dispersion in high capacity and high constellation systems. This is – to our knowledge – the first detailed study in this area for pre-compensation systems. Our main results show that the local oscillator phase noise determines the ...

Phase noise and jitter are two related quantities associated with a noisy oscillator. Phase noise is a frequency-domain view of the noise spectrum around the oscillator signal, while jitter is a timedomain measure of the timing accuracy of the oscillator period. This paper discusses the relationship between phase noise and jitter in free-running oscillators. The reader is referred to three othe...

| In this tutorial paper, we review fundamentals of oscillator phase noise emphasizing its physical picture based on the concept of phase di®usion. This review is intended to provide an essential understanding of phase noise rather than a comprehensive phase noise modeling. We then summarize several phase noise reduction techniques for various types of oscillators. Index Terms|oscillators, phas...

White noise generators can use uniform random sequences as a basis. However, such technology may lead to deficient results if the original have insufficient uniformity or omissions of variables. This article offers new approach for creating phase signal generator with an improved matrix autocorrelation coefficients. As result, generated signals white process absolutely intensities at eigen Four...
