Abstract
The invention relates to a method for transmitting at least K reference signals in a radio signal to be transmitted over a wireless communication system, said radio signal being intended to be emitted by an emitter comprising at least a transmit antenna configured for emitting on a number M of subcarriers S1, . . . , SM amongst which at least a number K of different subcarriers Sq+1, Sq+2, . . . , Sq+K are contiguous, the respective frequencies of the contiguous subcarriers Sq+1, Sq+2, . . . , Sq+K being ordered, said radio signal being provided by: inserting the at least K reference signals P1, . . . , PK so that the at least K reference signals P1, . . . , PK are respectively transmitted on the K contiguous subcarriers Sq+1, Sq+2, . . . , Sq+K; emitting the radio signal including the at least K reference signals.
