In particular, it concerns high speed transmission using layered space-time encoding architecture adapted to all types of propagation channels.The invention therefore proposes a digital signal transmission system comprising: a space-time encoder (1) receiving a flow of data to be transmitted d[i], formatting this data d[i] as symbol vectors v[k] of dimension P(P>1) and generating said symbol vectors v[k], and modulator-transmitters {2p}(1≦p≦P), each receiving one component of the symbol vector m[k] output from the space-time encoder (1), applying the constellation of a predetermined modulation to said symbol mp[k], and converting the symbol obtained ap[k] into a signal sp(t) presenting time diversity transmitted on said antenna (24p) connected to said transmitter (2p). To demodulate in parallel the Q signals of the space-time observation y _ ⁡ [ k ] = ∑ j = 0 J - 1 ⁢ ⁢ H y ⁡ ( jTs ) · a _ ⁡ [ k - j ] + b _ y ⁡ [ k ] where ā[k] is the symbol vector transmitted at instant t=kTs+i, Hy(t) the transfer function taking into account at least the transmission-reception, modulation, channel filters and the transmission-reception antenna gains and by(t) the noise, the invention proposes a two dimensional suitable estimator-demodulator.
