Information Theoretic Capacity of Cellular Multiple Access Channel With Shadow Fading

In the past, wireless systems were designed to accommodate a large number of voice and/or low data rate users. With the emergence and continuous growth of wireless data services, the value of a wireless network is not only defined by how many users it can support, but also by its ability to support high data capacity at localized spots. Shannon developed a mathematical theory for the single-link channel capacity in providing the framework for studying performance limits in communication. Shannon's work gave birth to the field of information theory. In information theoretic literature different approaches have been reported to determine maximum data rate and the means to achieve this under various assumptions and constraints.
