(2013). ‘Real-time validation of a SDR implementation of TDD WiMAX standard’, Proceedings of 5th annual Conference on Wireless Innovation Forum European Conference on Communications Technologies and Software Defined Radio (SDR-WInnComm-Europe 2013), Munich, Germany, 11-13 June 2013. pp. 27-35.http://hdl.handle.net/2183/35333[Abstract]: This paper focuses on the validation of an innovative software- defined radio architecture for a WiMAX system based on commercially available field-programmable gate array and digital signal processor modules. We provide a realtime implementation of a standard-compliant time-division duplex physical layer including a mobile and a base station as well as downlink and uplink communications, thus obtaining a full-featured physical layer. Additionally, a set of different configurations are supported as described in the standard and in the WiMAX Forum. The main contribution of the paper consists in a reproducible and repeatable validation of the implementation in representative scenarios. At the same time, a characterization of the performance exhibited by the system is provided based on bit error rate measurements carried out using a custom-made, real-time channel emulator.engTodos os dereitos reservados.
