METHOD AND APPARATUS FOR TRANSMITTING TRAINING SIGNAL IN WIRELESS LOCAL AREA NETWORK SYSTEM Russian patent published in 2014 - IPC H04B7/26 

FIELD: radio engineering, communication.

SUBSTANCE: invention discloses a method of transmitting a training signal which includes generating one or more first training signals for a first destination station and one or more second training signals for a second destination station by applying a mapping matrix P to a training signal generation sequence, mapping the first training signals and the second training signals to a plurality of antennae according to an antenna mapping matrix, and performing inverse fast Fourier transform (IFFT) on each of the first training signals and the second training signals mapped to the plurality of antennae and transmitting the training signals through the plurality of antennae.

EFFECT: controlling the increase in number of spatial streams by generating and sending a training signal.
