US Patent 10382240 FBMC-MIMO transmission/reception system with ML detection

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 and an ML detector 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.
