SPACE ENCODING WITH SPECTRUM SPREADING IN COMMUNICATION SYSTEM WITH MULTIPLE ANTENNAS Russian patent published in 2008 - IPC H04B7/216 H04J13/02 

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 N_D blocks of data symbols that must be transmitted in N_M intervals of transmission, where N_D ≥ 1 and N_M> 1; N_D amount of blocks is split into N_M 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 N_T amount of transmitting antennas during one transmission interval. Therefore, N_D amount of blocks of data symbols are dimensionally processed using N_M control matrixes and correspond the channel assembly.

EFFECT: space encoding with spectrum spreading in the system with multiple antennas.
