Abstract:
Method for preparing a transmission signal with an instantaneous amplitude A and an instantaneous phase &phgr;0, by means of n amplification cells, with n as a whole number at least equal to 2, each amplification cell giving a whole number, at least equal to 2, of output discrete levels, including the level zero, characterized in that, considering the primary vector of the modulus A with an argument &phgr;0, it consists in determining n secondary vectors with a vector sum equal to the primary vector, these secondary vectors being chosen in a one-to-one relationship with the n cells and each having a modulus with a value corresponding to one of the discrete levels of the cell with which it is in a one-to-one relationship and a phase, in controlling each of the n cells so that it gives a signal with instantaneous amplitude and phase whose values correspond respectively to the values of the modulus and of the argument of the secondary vector in a one-to-one relationship with the cell considered and in summing up, in an energy-coupling device, the signals given by the n cells.
