Receiver with iterative channel estimation using a return loop (turbo estimation)

摘要

The invention concerns a receiver with data transmission channel turbo estimation, comprising at least one channel estimator (10) and a symbol detector (20), as well as a return loop (50) to the channel estimator (10) for returning transmission data such as they have been estimated by the symbol detector (20) upon a previous iteration. The invention is characterized in that the channel estimator (10) and the symbol detector (20) are designed to implement a series of operations each resulting in providing an estimation of at least one distinct transmission data, the channel estimator (10) being designed to eliminate from a group of reception data one part thereof which is dependent upon the transmission data to be estimated, and, based on said reception dependence-free data, to provide a determination of the propagation channel itself dependence-free, the symbol detector (20) proceeding with the operation by estimating the transmission data from said propagation channel.
