The paper deals with signal degradation due to noise and nonlinear distortion in the forward channel of HFC television network. A mathematical model of the optical channel is presented that makes it possible for the following ...
A general overview of most problems appearing when signals are transmitted in the fiber optic part of a CATV system is made. Some basic theoretical dependencies, as well as numerical methods suitable for computer simulation, ...
In this paper six algorithm for carrier frequency recovery are examined, namely D&M, L&R, Fitz, M&M, Modified M&M and Kay. A mathematical description of algorithms and expressions for determining the frequency ...
