Abstract:
1. A method of sending data performed by a sending device and comprising: sending data by at least a first data signal and a second data signal, said data being divided into data blocks of identical size including a header field, which is a cyclic prefix and has a predetermined size, said data signals being sent to at least one data processing device adapted to apply a cyclic autocorrelation function with parameter k to the data blocks of the first and second data signals enabling said first and second data signals to be identified, wherein the value of the parameter k is a natural integer and is a multiple of a ratio between the size of said data blocks and the predetermined size of the header field; and if said first data signal needs to be separated from said second data signal, modifying the size of the header field of the data blocks of said first data signal before sending said first data signal, so that the size of the header field of the data blocks of said first data signal is different from said predetermined size of the header field of the data blocks of said second data signal, the value of the parameter k and the size of said data blocks remaining unchanged.
