Prototyping processing-demanding physical layer systems featuring single or multi-antenna schemes

In the past years numerous algorithms, schemes and techniques have been proposed, in order to improve the performance of the wireless multi-antenna communication systems. Real-time multi-antenna testbeds are offering the means to analyse the real-world performance, implementation cost and feasibility of such novel techniques, accounting for hardware limitations and software constraints. This paper presents the physical-layer (PHY) design, implementation and validation of a high-performance real-time mobile WiMAX transceiver, accounting for low-level deployment issues and signal impairments. A first evaluation of the acquired results for both Single Input Single Output (SISO) and Multiple Input Multiple Output (MIMO) system-configurations, demonstrates the performance of the system using real-time channel emulation.
