Abstract
A method for determining a shifting parameter P to be used by a telecommunication device for mapping symbols on sub-carriers, the telecommunication device including at least two transmit antennas, the symbols being transferred through each antenna of the telecommunication device on at least an even number K, strictly greater than two, of sub-carriers allocated to the telecommunication device. The telecommunication device transfers on a first antenna on each sub-carrier 'k', a signal representing a symbol 'X' in the frequency domain. The telecommunication device transfers on a second antenna on each sub-carrier ‘k’, a signal representing a symbol ‘X'’ derived from the signal transferred on the first transmit antenna, for each frequency k, by the formula X′=ε(−1)X*. Sub-carriers grouped in at least two clusters are allocated to the telecommunication device, and the shifting parameter p is even and determined according to clusters of sub-carriers allocated to the telecommunication device.
