Real-time validation of a SDR implementation of TDD WiMAX standard
[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.This work has been partially supported by Indra Sistemas
