FIELD: electrical communication equipment.
SUBSTANCE: invention relates to a wireless communication technique and can be used in channel estimation in a wireless communication system. In a system with multiple inputs and multiple outputs, the wireless node's receive chain demodulation function is improved to include phase tracking. Instead of tracking the phase throughout the data symbols, which involves great difficulties in very high-capacity wireless networks, VHT long training fields (LTF) embedded in the frame preamble are used to track the phase. Transmitting chain of wireless communication devices contains scheme for distribution of preamble and payload data from the compiled transmission data stream to plurality of parallel spatial flows, wherein set of identical information is displayed in the preamble at each of a plurality of parallel spatial streams for estimating a set of channel characteristics and a phase error when receiving; and scheme for transmission of a plurality of parallel spatial streams with multiple transmitters.
EFFECT: technical result is an increase in the accuracy of the channel estimation.
