Multi-user detection method for a receiver in a MC-CDMA telecommunication system |
摘要 |
The present invention concerns a multi-user detection method for a receiver in a MC-CDMA telecommunication system, each communication to or from a user of the system being coded with a signature, the signal received by said receiver being decomposed into a first plurality of frequency components, where the frequency components are subjected to a first filtering matched to the respective signatures of a second plurality of users and to the common or the respective responses of the transmission channels associated to the communications to or from said users; a first estimation of the symbols transmitted to or by the users is obtained from the output of the first filtering; a multi-user interference is derived from the first estimation and subtracted from the output of the first filtering to provide a cleared output; a second estimation of the symbols transmitted to or by the users is obtained from the cleared output.
