A concept of using MIMO technology in millimeter range wireless communications systems with orthogonal frequency division multiplexing is considered. The concept is based on dividing transmitting and receiving multi-element antenna arrays into separate sub-arrays with analogue radiation pattern shaping and on using two most powerful space sub-channels for information transmission. Sequence and structure of transmitted packets between transceivers are suggested that allow for obtaining information on communications channel based on additional training sequences without feedback channel. Modeling results of communications system’s operation in conditions of multipath frequency-selective fading channel are presented.
