A Performance Comparison of Candidate 4G Air-Interfaces in a Simulated Cellular Environment
Source: University of the Witwatersrand
Development of the Fourth Generation of mobile communication systems, or 4G, has already begun in various organizations and research institutions worldwide. There is currently no single conclusive definition for 4G systems, and the process of 4G standardization will only begin after the World Radiocommunication Conference in 2007. The purpose of this paper is to evaluate the performance of two candidate 4G air-interface architectures, namely OFDMA and MC-CDMA, so that a recommendation can be made as to which architecture should form the core component of a new 4G access network system.
