FIELD: information technology.
SUBSTANCE: matrix for phase shift based precoding can be generalised and defined in spatial domain by product of diagonal matrix for phase shift by unitary matrix for supporting orthogonality. Diagonal matrix can be expanded by product of precoding matrix for power multiplication in the channel by the mentioned diagonal matrix for phase shift.
EFFECT: higher efficiency of communications and generalisation and extension of phase shift based precoding.
