Abstract:
A transmitter of an FBMC-MIMO system in which, for each FBMC-OQAM modulator associated with a transmission antenna, the symbols of a block to be transmitted are grouped in pairs, the input symbols in a pair being combined to output first and second combined symbols, the combined symbols being input to the FBMC-OQAM modulator. The invention also relates to a receiver including an FBMC-OQAM demodulator ( 410 1 , . . . ,410 N R ) and an ML detector ( 450 k ) from the observables obtained, for each reception antenna. The used ML detection allows for not being affected by intrinsic interference and obtaining a high degree of diversity without increasing the number of antennas.

Claim (Index 7):
The receiver of an FBMC-MIMO transmission system according to  claim 6 , wherein a maximum likelihood detection module receiving two projected real vectors y % k , y % k , searches for the most probable transmitted symbols {circumflex over (x)} k , {circumflex over (x)} k\u22121  by means of x ^ k , k + 1 = arg \ue89e \ue89e min \ue89e x k , x k + 1 \ue89e \uf605 y k , k \u2032 % - R k , k \u2032 22 \ue8a0 ( A ) \ue89e x k , k + 1 \uf606 2 \ue89e \ue89e with \ue89e \ue89e \ue89e x k , k + 1 = ( x k x k + 1 ) , y k , k \u2032 % = \ue89e ( y k % y k \u2032 % ) , R k , k \u2032 22 \ue8a0 ( A ) = ( R k 22 0 0 R k \u2032 22 ) R A  in which the matrices R k 22  and R k\u2032 22  were obtained by QR decomposition of matrices {grave over (H)} k  and {grave over (H)} k\u2032  respectively, and R A  is the matrix defined by: R A = ( a 11 a 12 0 0 L 0 0 0 L 0 0 0 0 L 0 a 11 a 12 0 L 0 0 0 a 11 a 12 O 0 0 0 O M M M O L L O O O O M 0 0 L O L L L 0 a 11 a 12 a 21 a 22 0 0 L 0 0 0 L 0 0 0 0 L 0 a 21 a 22 0 L 0 0 0 a 21 a 22 O 0 0 0 L 0 M M O L L O O O O M 0 0 0 L L L L 0 a 21 a 22 ) in which A = ( a 11 a 12 a 21 a 22 ) is the matrix representing the linear combination of symbols x k , x k+1 , used in transmission.
