<p>The invention concerns a transmission signal (S) resulting from the modulation of a data digital signal by a modulation function dependent on time (t), said data signal being formed by a series of bits each (bk) identified by its rank k and having a duration T, said transmission signal (S) consisting in a summation indexed on the rank k of the product of the constant complex j to the power of k, of the modulation function h(t-kT) and of an input signal. The input signal F(k) being a function of the data signal (bk), the modulation function h(t-kT) is a Gaussian function of the time t.</p> |
