Analyzing of multi service backhaul network based on IP radio access network technology

Basing on the optical transmission theory, the technology devolvement direction and long term evolution direction of fixed network and mobile bearer network status is analyzed. The business transformation of telecom business needs is discussed around the customer value and high quality network construction ideas. With the communication technology, the domestic IP RAN (Radio Access Network) bearer network is analyzed in detail. And the IP RAN bearing network service bearing network types and related properties are discussed, in order to provide relevant reference scheme for domestic bearing network construction. In this paper, this data transmission network system is studied using analytical approaches. We analytically calculate the variance of the phase rotation term for each subcarrier when the pilot subcarriers are uniformly distributed or centered over the signal transmission.
