Patent ID: 7366232

Claim:
A method for determining at least one traffic parameter in a data transmission system comprising at least one transmitter and a receiver, said receiver including a modem with an equalizer and a decoder as part of a signal processing card, and a management card, the method comprising: transmitting via a high frequency channel reflected by ionosphere an initial training sequence by using known modulation symbols to said equalizer; first determining at least one piece of data given by the equalizer, the at least one piece of data including an equalization error E i of the initial training sequence; second determining in said management card at least one traffic parameter in taking account of the data provided, a required quality of service QoS, and a relationship linking the required quality of service and the equalization error E i ; transmitting said at least one traffic parameter to said decoder; and transmitting traffic information, after said decoder is configured based on said at least one traffic parameter, from said decoder to a user not through said management card.
