Modeling of the multi-carrier modulation benefits for data transmission

More efficient data transmission is an important element for increasing an overall transmission performance in broadband access networks. Advanced access network infrastructure can have a dual nature. First, it may entirely consist of optical elements, which mean that the network has a nature of a passive optical access network. In addition, in a network topology there can be found elements that work with signals in an electrical form. Then, the network has a character of a hybrid access network. Modulation principles for user signals transmission in the second part of the hybrid access network belong to the group called multi-carrier modulation. This paper is focused on finding a more suitable simulation principles used when calculating the benefits of multi-carrier modulation used for user data transmission. Consecutive chapters describe a simplified method of modeling the user data transmission performance with regard to the real parameters of the transmission environment. Concrete results for typical situations are calculated and discussed.
