Abstract:
1. A digital signal transmission system comprising: a space-time encoder receiving a flow of data to be transmitted d[i], encoding this data d[i] as symbol vectors m[k] of dimension P(P>1) and generating said symbol vectors m[k], and P modulator-transmitters { wherein the transmitters are adapted to transmit signals s(t) with time diversity, wherein P modulator-transmitters { 2 p }: each produce said symbol a each form a filter of function h each generate at their respective transmission antennas the signal s wherein the digital signal transmission system further comprises a wave form h p , wherein h 1 ≠h 2 ≠ . . . ≠h P for all values of p wherein (1≦p≦P).
