Method for sending pulses in a transmission channel

A method of estimating parameters of a transmission channel carrying pulses sent from a sender device to a receiver device, wherein the pulses represent information symbols, with each of these pulses being associated with a time slot in a symbol time, the method comprising:

• receiving a training sequence by the receiving device before receiving payload information, with said sequence being made up of two parts:
• a first part of the training sequence including at least one pulse of energy that is greater than the energy of a pulse carrying payload information, with there being a large number of time slots between the sending of said pulse and the sending of the next pulse;
• and
• a second part of the training sequence including a set of pulses known in advance and similar to the pulses used for carrying payload information, the energy of each of these pulses of the second part being equivalent to the energy of a pulse carrying payload information;
• and
• estimating parameters of the transmission channel as a function of the training sequence.
