Abstract
The invention concerns digital signal transmission. 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: To demodulate in parallel the Q signals of the space-time observation where[k] is the symbol vector transmitted at instant t=kTs+i, H(t) the transfer function taking into account at least the transmission-reception, modulation, channel filters and the transmission-reception antenna gains and(t) the noise, the invention proposes a two dimensional suitable estimator-demodulator.
