Selective Activation of VAMOS-2 Mode

摘要

Method of data processing for selectively activating, at a mobile station (1, 2), a mode of communication related to VAMOS-2 technology, the method comprising the steps of:—receiving a first signal of a first subchannel (C1), the first signal containing a first training sequence (mwant), and receiving a second signal of a second subchannel (C2), the second signal containing a second training sequence (mosc), the second signal being orthogonally multiplexed with respect to the first signal,—using the first training sequence and the second training sequence to:—determine a value of a parameter (α) defining a ratio between the first subchannel power and the second subchannel power, and—determine a signal to noise ratio estimation, and—determining, using the parameter value and the signal to noise estimation, whether the said mode of communication has to be activated.
