This paper proposes a new scheme of position location for radio terminals using MIMO-OFDM signal. First, this paper describes on a system configuration of LCX linear cell MIMO system and its research issues. Second, to observe channel responses depending on the terminal location, impulse responses are measured in the anechoic chamber. Third, principle of operation for positioning the radio terminals using multiple antennas and its signal processing using OFDM are described. The 2x2 spatial division multiplexing is successfully carried out using 2-port LCX as a transmitting antenna. Time difference of arrival (TDOA) is estimated at receiver by using its channel estimation function. From the experiments, the validity of averaging operation between estimated TDOAs are found to enhance positioning precision.
