IDMA-Based Improved Multi-User OFDM System For Next Generation WLAN

Abstract

The demand for mobile broadband not only enhanced the current communication applications, but also generated new services which are highly reliant on this connection. Since wireless applications are on the rise in the future systems, new technologies that can offer high capacity and QoS have to be incorporated. It is predicted that the future communication networks will face issues in managing large and diverse data traffic and a large number of users so that new sophisticated multiple access (MA) schemes will be needed. Since the focus of research is gradually moving to the development of even more effective MA schemes, it is important to compare various options to select the most suitable one. Thus the main purpose of the paper is to gave a compressive overview of most popular or the newest MA schemes.
