1. Method for equalizing filterbank based multicarrier modulations, comprising the steps of: a. serial-to-parallel converting the received signal at a serial-to-parallel converter ( 421 ) into a first plurality (M) of parallel streams of subcarriers; b. processing each subcarrier of the first plurality (M) of parallelized subcarrier signals by a second plurality (K) of parallel second filterbanks ( 422 , 422 ′, 422 ″,. .. ); and c. weighting the output of said K parallel second filterbanks with weights ( 430 , 431 ,. .. ) in order to form a new set of M signals.
