Abstract: Disclosed are a method and apparatus for estimating a Multiple Input Multiple Output (MIMO) channel. A signal transmission method for estimating the MIMO channel via 2N transmission antennas (N is greater than or equal to "1") includes generating a code having a predetermined Interference Free Window (IFW), and transmitting the code via two transmission antennas.

Abstract: A multiple antenna wireless channel measuring system and a method thereof for measuring a bidirectional radio channel using the time control signal are provided to measure radio channel as wireless measurement mode selected from TDD(Time Division Duplex), FDD(Frequency Division Duplex), and a simplex mode. A controller selects a radio measurement mode, generates measurement signal and receives the measured parameters. A base-band processing unit(200) sets up the transmit receive frequency bandwidth based on the radio determination mode and receives parameters. A synchronization unit(210) generates transmission/reception signal and supplies the transmission/reception signal to the base-band processing unit. An RF(Radio Frequency) processing unit switches an antenna according to the timing control signal.
