OFDMA-based Broadcasting and Access Hybrid Network

Communication networks can be conveniently categorized into two types: those that provide point-to-point connectivity (e.g., cellular) and others that are ´broadcast´ in nature (such as TV and radio) that are inherently ´point-to- multipoint´. This paper introduces an OFDMA-based cellular infrastructure that supports both broadcasting and cellular on a single-frequency platform. The fundamental limits of these hybrid modes of communications are investigated, along with the network capacity under different configurations based on cooperative transmission.
