Abstract:
1. A method of radio data emission, by an emitter including at least two transmit antennas, each antenna transmitting on at least an even number ‘N’, strictly greater than 4, of different frequencies, the method comprising: emitting, on a first antenna and during a given time slot on each frequency ‘k’, with k=0 to N−1, a signal representing a complex symbol ‘X emitting, on a second antenna and during the same time slot, on each frequency ‘k’, with k=0 to N−1, a signal representing a symbol ‘Y wherein for a given integer value M chosen as an even value between 0 and N−1 inclusive, the symbol Y Y resulting in a pairing of frequencies according to a pairing scheme and applying to each pair of frequencies a variant of an Alamouti code on symbols to be emitted.
