APPARATUS AND METHOD FOR CALCULATING RECEIVE PARAMETERS FOR AN MIMO SYSTEM
First Claim
1. An apparatus for calculating receive parameters for an MIMO system comprising a plurality of individual transmission sections, a transmission section comprising a transmit circuit being adjustable by a transmit parameter, and a plurality of individual users, a user comprising a receive circuit being adjustable by a receive parameter, comprising:
- a calculator for calculating a receive parameter for a first selected data stream for a first user of the plurality of users using a channel information for a transmission channel between the user and a first individual transmission section, to which the user is associated, and for calculating a receive parameter for a second selected data stream for a second user of the plurality of users associated with a second different individual transmission section using a channel information between the first user and the second individual transmission section, to which the second user is associated with, or using the calculated receive parameter for the first user, wherein an interference caused by a transmission of an individual transmission section at a user in a different transmission section is reduced or eliminated.
