Beskrivelse

Multiple‑Input Multiple‑Output (MIMO) radio channels arising from the deployment of multiple element antenna arrays at both ends of a wireless communication link have the potential to increase the overall system capacity or the peak data rates of a given user. Nevertheless, exploiting the benefits of a multiple antenna configuration is not always straightforward. The optimal solution requires the availability of Channel State Information (CSI) at the transmitter, which can only partially be fulfilled in practise. To test MIMO system performance a link level MIMO channel simulator has be build during the European IST projects METRA and I-METRA (Intelligent Multiple Element Transmit and Receive Antennas). Following ongoing standardisation activities in 3GPP/3GPP2 and IEEE the link level channel simulator has been customised by FUNDP-INFO inline with SCM-134 and IEEE 802.11 HTSG Channel Model Special Committee recommendations. A MATLAB version of the simulator is available free of charge from and has already been downloaded by over 140 third parties. Above link level MIMO channel simulator has been combined with general DS-CDMA MIMO SINR derivations and a cellular scenario simulation concept to generate a user-performance data base. A network simulator can thereafter use the database to retrieve user performance and asses the performance of different network processes like fast channel quality dependent scheduling, Adaptive Modulation and Coding (AMC) as well as Hybrid Automatic Retransmission Request (HARQ). This look-up approach allows very run time efficient network simulations and is therefore ideally suited for network level algorithm development. The general simulation concept as presented above was accustomed to specifically assess the performance of UMTS High Speed Downlink Packet Access (HSDPA). The work has been co‑sponsored by the European Union, IST research programme and Nokia Networks.
