MODE OF SUPRESSION OF MULTI-USER INTERFERENCE AND A BLOCK FOR SUCH SUPRESSION Russian patent published in 2007 - IPC H04Q7/32 H04B7/26 

FIELD: the invention refers to radio technique particularly to multi-user detection in communication systems of plural access with code division of channels.

SUBSTANCE: the proposed mode has in essence the following stages: demultiplexing and squeezing of the input signal of the main diapason with using a block of pressure. Then the squeezed signal is pressed according to Walsh algorithm in various channels to divide the user's channels. A separate flow of the bits of each channel is multiplied on interfaced signal of the output evaluative value from the block A of control evaluation to eliminate influence of multi-beam dying down. The bits flow is introduced after multiplication into a solver to make decisions. They fulfill stages for definition of the step for making decision, use two other blocks B and C of control evaluation and also data about quantity of users, channel and service types, provided by the system. The invention may control more accurately the decision making according to the signal and restore the signal, and also work out these decisions.

EFFECT: increases accuracy of suppression of multi-user interference.
