FIELD: information technology. ^ SUBSTANCE: space encoding with spectrum spreading is performed in the system with multiple antennas for randomising the "active" channel traced by the receiving object, for every block sent, data symbols on the transmitting object. The data is processed for obtaining ND blocks of data symbols that must be transmitted in NM intervals of transmission, where ND >= 1 and NM> 1; ND amount of blocks is split into NM subblocks of data symbols, one block for each transmission interval. The control matrix is chosen for every subblock, each subblock of data symbols is processed dimensionally using the control matrix chosen for this sub block to obtain transmission symbols that are additionally processed and transmitted via NT amount of transmitting antennas during one transmission interval. Therefore, ND amount of blocks of data symbols are dimensionally processed using NM control matrixes and correspond the channel assembly. ^ EFFECT: space encoding with spectrum spreading in the system with multiple antennas. ^ 54 cl, 7 dwg |
