ITERATIVE SUCCESSIVE INTERFERENCE CANCELLATION IN MU-MIMO USING INTERFERENCE WHITENING AND CHANNEL REESTIMATION

摘要

A method implemented by a receiver of a telecommunication device comprising receiving a signal y corresponding to an intended signal u being turbo-encoded, bits-to-symbols converted, and then sent on a MIMO time-dispersive channel having a dispersion matrix H, applying an interference-cleaning process on an initial signal Ŝ _LIN comprising a spatial interference whitening, a MIMO joint detection, and then a turbo-decoding, subtracting from the initial signal Ŝ _LIN a subtraction signal (Ḣ _ISI Ŝ) determined by performing an interference-extracting process on the result of the application of the interference-cleaning process, determining an estimated signal û indicative of the intended signal u by performing the interference-cleaning process on the result of the subtracting.
