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 17):
The method of  claim 14 , wherein computing the signal to noise ratio of each user comprises:\n obtaining a channel matrix, wherein the channel matrix is a two column and n*N row matrix corresponding to signals received by the n*N antennas of the base stations; decomposing the channel matrix into three matrices using Singular Value Decomposition (SVD) to obtain three matrices, wherein the channel matrices are n*N\u00d72 matrix which is denoted by \u201cU\u201d, 2\u00d72 diagonal matrix which is denoted by \u201cS\u201d and other matrix is a 2\u00d72 precoder matrix which is denoted by \u201cV H \u201d, where matrix \u201cV\u201d is sent to the user and the user uses it as precoder before transmission; expressing a new effective channel matrix as a product of two matrices \u201cU\u201d and \u201cS\u201d; expressing, for each user, two new pseudo users, with effective channel vector as first and second column of product of \u201cU\u201d and \u201cS\u201d; and applying Interference Rejection Combining (IRC) function on n*N signals received by the plurality of antennas present in the plurality of base stations using the effective channel vectors of all the pseudo users.
