FIELD: information technology.
SUBSTANCE: transmission signal undergoes space-time coding on a plurality of space-time antenna groups, wherein each space-time antenna group is associated with a particular space-time code. Based on each signal in each space-time antenna group, a beam is formed for a plurality of antennae in the given space-time antenna group. Each antenna in the plurality of antennae in the space-time antenna group is assigned a separate weight coefficient relative the other antenna in that space-time group. Each weight coefficient can have defined amplitude, phase or a combination of amplitude and phase. The weight coefficients can be static or dynamic. For dynamic coefficients, the amplitude, phase or combination of amplitude and phase can vary with time.
EFFECT: transmission diversity.
