Abstract(in English) Recently, Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) has attracted much attention as a technology achieving high-speed wireless transmission with a limited bandwidth. However the theoretical analysis and various basic computer simulations are employed to realize MIMO-OFDM systems, a few researches about hardware implementation of MIMO systems have been done. Thus, we developed the transceiver and software which can evaluate 4×MIMO-OFDM transmission with 100MHz bandwidth. This paper describes the brief overview of this MIMO-OFDM transceiver and software and clarifies the basic characteristics of this equipment in an actual indoor environment. Moreover, we evaluated the frequency efficiency when assuming the wireless LAN systems by obtaining the Bit Error Rate of this MIMO-OFDM transceiver.
