Abstract
A method and device to equalize a signal received by a receiver after having traveled through a transmission channel, said signal comprising at least one data block and several probes located on either side of the data block. The method comprises at least one step in which the impulse response of the channel is estimated before and after a data block n in taking account of the probes (Probe n−1 and Probe n) located on either side of the data block n and also of the probes that precede and follow the Probes n−1 and Probe n, said probes being weighted and combined with one another. Use in a BDFE type device.

A method for the equalization of a signal received by a receiver after it has traveled through a transmission channel, said signal comprising at least one data block and several probes located on either side of the data block, wherein the method comprises a step in which the impulse response of the channel is estimated before and after a data block n in taking account of the probes (Probe n−1 and Probe n) located on either side of the data block n and also of the probes that precede and follow the Probes n−1 and Probe n, said probes being weighted and combined with one another.
A device used to equalize at least one signal having traveled through a transmission channel, said signal comprising at least one data block and several probes located on either side of the data block, wherein the device comprises at least one means receiving the signals and adapted to estimating the impulse response of the channel before and after a data block n in taking account of the probes (Probe n−1 and Probe n) located on either side of the data block n and also of the probes that precede and follow the Probes n−1 and Probe n, said probes being weighted and combined with one another and at least one BDFE type device.
