The detection and estimation algorithm, implemented at the receiver, is based on a version of the expectation maximization (EM) technique which is very suitable for the multicarrier signal formats. Application of the EM-based algorithm to the problem of iterative data detection and channel estimation leads to a receiver structure that also incorporates a partial interference cancelation. Computer simulations show that the proposed algorithm has excellent BER end estimation performance.trinfo:eu-repo/semantics/closedAccess[No Keyword Available]Conference Object10.1109/SIU.2007.42988022-s2.0-50249136065N/AN/A
