  • Transmission/reception methods and modules for a multiple-carrier multiple-antenna system using training sequences
    Patent number: 8290081
    Abstract: The present invention relates to a transmission method and device suitable for a system using Nt transmit antennas TXi and Nr receive antennas RXj. The symbols transmitted are inserted in a time-frequency frame that contains a training sequence. Each training sequence is constructed from replicas of a basic training sequence. At least one of the training sequences includes at least two replicas at least one of which is phase offset.
    Type: Grant

  • Method and device for receiving a data signal consisting of symbol blocks and corresponding computer program
    Patent number: 8077766
    Abstract: A method is provided for receiving a received data signal including at least one symbol block received and representative of a source signal. The method includes at least one iteration for improving an estimate of the received signal and including the following steps, for a current equalized symbol block: obtaining one or more decided bits, by bit-by-bit decoding a current subset of bits; updating one or more symbols, according to the decoded bit or bits, delivering an updated block of estimated symbols; determining a block of equalized symbols enhanced by canceling interferences, taking account of the updated block of estimated symbols.
