A channel estimation sequence (SE) embedded in a carrier wave and configured to be transmitted by a transmitter (1) to a receiver (2) via a channel (3) to implement a channel estimation method, the channel estimation sequence consisting of two concatenated sequences (S and G) respectively consisting of two complementary sequences (s and g). The channel estimation method includes, on the transmitter side, transmitting the channel estimation sequence and, on the receiver side, a correlation process consisting of correlating the received signal with the first (s) of the said complementary sequences, correlating the received signal with the second (g), delayed complementary sequences, adding the results of the two correlations, and deducing the characteristics of the channel (3) from the result of the correlation process. The two complementary sequences (s and g) are extended periodically by extensions (esf, esd and egf, egd) which constitute replicas of their starting part and/or ending part and which are respectively concatenated at the end and/or start of the sequence.
A method of estimating a characteristic of a transmission channel in a receiver, comprising:
A receiver, comprising:
A receiver configured to receive a channel estimation sequence (SE), said channel estimation sequence including concatenated sequences S comprising a sequence s and an extension esd comprising a copy of a front portion of the sequence s, and G comprising a complementary sequence g and at least one of an extension egf comprising a copy of a rear portion of the sequence g and an extension egd comprising a copy of a front portion of the sequence g, said receiver comprising:
