Patent ID: 7924945

Claim:
Method for the reception of a data signal, implementing N R receiving antennas, where N R is greater than or equal to 2, said data signal having undergone a channel encoding and a spatial multiplexing before emission and being emitted on N T emission antennas, where N T is greater than or equal to 2, each of said antennas emitting a part of said signal, wherein said reception method comprises: estimating a transmission channel between said emission antennas and said receiving antennas; and at least one iteration to improve an estimation of the received signal, depending on said received signal and a preceding estimation of said received signal, said iteration comprising the steps of: filtering said received signal, delivering a filtered signal; determining an interference affecting said received signal, implementing a multiplication of said preceding estimation of said received signal by a matrix representing interferences due to the transmission channel for the transmission of said received signal, said determining operation delivering an estimated interference; subtracting said estimated interference from said filtered signal so as to obtain an improved signal; equalizing said improved signal, delivering an equalized signal; and estimating the data signal emitted, called an estimated signal, from said equalized signal.
