Abstract
The disclosure relates to a method for receiving a data signal by Nreceiving antennas. The data signal undergoes, before transmission, a channel coding and is transmitted on Nantennas each transmitting a portion of this signal. Upon reception the transmission channel between the transmitting antennas and the receiving antennas is estimated. The method of the aforementioned type involves at least one iteration for improving an estimation of the received signal according to the received signal and involves a preceding estimation of said received signal, comprising the following steps: filtering this received signal; determining an interference affecting the received signal while furnishing an estimated interference; subtracting this estimated interference form the filtered signal whereby obtaining an improved signal; equalizing this improved signal and furnishing an equalized signal, and; estimating, from this equalized signal, the emitted data signal, called the estimated signal.
