<p>The present invention concerns multi-user detection method of symbols transmitted over a downlink of a multi-carrier code division multiple access telecommunication system, the symbols for a user of the system being spread with a signature over a plurality of carriers, the signal received by a user being decomposed into a plurality of frequency components and said frequency components being despread with said signature. Prior to despreading, said frequency components are equalised by multiplying each of said components with a coefficient, said coefficients taking into account an interference level, after despreading, between the symbols for said user and the symbols for the other users of the system. The present invention concerns also an MC-CDMA receiver implementing such a multi-user detection method. <IMAGE></p> |
