MIMO Channel Hardware Simulator for LTE and 802.11ac Wireless Communication Systems

le jeudi 3 octobre à 10 h 30 en amphi Bonnin de l’INSA de Rennes.

Résumé :

To evaluate the performance of the emerging mobile and wireless communication systems, a Multiple-Input Multiple-Output (MIMO) channel hardware simulator is designed and implemented using the recent communication standards. It provides the processing speed required to the real-time performance evaluation and allows comparing various systems in the same test conditions. The objectives of this work mainly concern the MIMO channel models and the digital block architecture of the hardware simulator.

The hardware simulator can be configured with Long Term Evolution (LTE) and Wireless Local Area Network (WLAN) 802.11ac signals. It uses standard channel models, as 3GPP LTE and TGn IEEE 802.11n. It also allows replaying measurement results obtained with the MIMO channel sounder designed and realized at our laboratory. In fact, data obtained during measurement campaigns onboard a ship and for outdoor-to-indoor environments were used. The measured impulse responses are pre-processed in order to make them compatible with LTE or 802.11ac signals. Moreover, time-varying channel models are obtained using Kronecker model with Rayleigh fading.
