Device and Method for the Optimal Estimation of Distortion of a Transmission Medium, Comprising the Sequential Emission of Pairs of Quadrature Complementary Sequences

A method of sending a signal through a transmission medium over a channel using a device comprising a transmitter;

• the transmitter comprising a pulse generator, a preamble generator block, a quadrature modulator and an upconverter operatively coupled to the preamble generator, and a composition block;
• the method comprising the steps of:
• receiving a pulse from the pulse generator at the preamble generator block;
• generating a preamble in response to the pulse with the preamble generator block by using at least one pair of complementary sequences or codes, with A1,B1 being one of the at least one pair and A2,B2 being the other of the at least one pair, with each of the at least one pair of sequences or codes being of length L;
• with the preamble generator block applying codes A1 and A2 to a phase signal I, and therafter applying codes B1 and B2 to a phase signal Q;
• quadrature modulating and upconverting the phase signal I and thereafter the phase signal Q using the quadrature modulator and the upconverter;
• with the composition block generating a composed signal from the quadrature modulated and upconverted signals from the quadrature modulator and upconverter;
• and
• transmitting the composed signal to the transmission medium over the channel.
