摘要： A method of allocating a plurality of subbands (SBi) to a plurality of streams (FLj) of a multichannel link in a multicarrier modulation communications system, each stream (FLj) being successively defined in a communications frame of said multichannel link by a number Mj of bits to be transmitted and a noise margin Γj. Each subband (SBi) is associated with a normalized signal-to-noise ratio (SNR0)i on the multichannel link. The subbands (SBi) are classified in a specific order of the normalized signal-to-noise ratios (SNR0)1. An energy Ei per subband (SBi) is determined by a binary allocation algorithm. For each stream (FLj) taken in the order of said frame, a number Nj of consecutive subbands (SBi) taken in the order of normalized signal-to-noise ratios is allocated so that the sum of the numbers nij of bits in each subband (SBi) allocated to each stream (FLj) is equal to Mj where: M j = ∑ i = 1 N j  n ij the number nij of bits being defined by: nij=log2(1+E1·(SNR0)i/Γj).
