Abstract:
A method for improving signal to noise ratio in an uplink transmission. The method includes determining a plurality of combinations of “N” possible users to be selected among “X” users that are transmitting signals to a base station comprising “n” number of antennas, where n>=N, wherein selected “N” users transmit on a same sub-carrier; computing signal to noise ratio (SNR) of the signals received from each of the users among the determined combination of “N” possible users; and selecting at least one combination among the plurality of combinations of “N” possible users, such that, a combined signal to noise ratio of the selected combination is maximum among all combinations.

Claim (Index 22):
The method according to  claim 21 , wherein effective channel matrix of the first user is (U\u00d7S) and transmit precoder is \u201cV\u201d, wherein computing transmit precoder of the first of the (n\u22122) users comprising computing \u201c\u0398\u201d using the PDA [V, \u0398]=\u03c8[U, h, k], wherein \u201cU\u201d is obtained from SVD of the channel matrix of the first user, \u201ch\u201d is the channel matrix of the first of the (n\u22122) users, \u201ck\u201d varies from 3 to \u201cn\u201d, wherein for each value of \u201ck\u201d, corresponding \u201cV\u201d and \u201c\u0398\u201d are obtained, wherein the transmit precoder of the first of the (n\u22122) users is \u201cV\u201d that corresponds to the maximum value of \u201c\u0398\u201d obtained when \u201ck\u201d varies from 3 to \u201cn\u201d, wherein effective channel vector of the first of the (n\u22122) users is a product of channel matrix \u201ch\u201d of the first of the (n\u22122) users and the transmit precoder \u201cV\u201d of the first of the (n\u22122) users.
