Claim One:
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 ″,. .. ), wherein said processing of the subcarrier signals is performed using a filter generated by frequency translation of an original filter hereinafter referred to as “prototype”, and where the prototype for each of the parallel second filterbanks is obtained by performing successive time-domain derivatives of the original filter; 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.
