Abstract:
A method for transmitting multiple communications of different types, in particular sporadic (MTC) or cellular (broadband) communication including symbols to be transmitted, corresponding to communication services implementing a modulation having M subcarriers of the FBMC-OQAM or OFDM-OQAM type. The method uses linear frequency filtering of a sequence of length N including symbols having L coefficients that are parametrizable according to the communication, L, N, and M being natural numbers, so as to generate N+L−1 symbols, reducing out-of-band spurious emissions. The method also uses, no matter what the communication is, a single frequency/time transform (IFFT) having a size M, where N
