Implementation of a WiBro system using GPU

Abstract

This paper presents an implementation of a communication system which operates on a realtime basis by using a graphic processing unit ( GPU ). In order to cope with an extremely highspeed data rate in modern communication systems, system processor should support the high system throughput and high operation complexity. GPU can satisfy the requirement of high complexity by processing a lot of data in parallel. Also, GPU provides a convenient operation system which enables relatively easy implementation of various waveforms. In this paper, we implement WiBro system and demonstrate the performance in realtime.
