A filter bank ( 10 ) and receiver including the filter bank ( 10 ) that is designed for processing a baseband signal of a received continuous phase modulated signal S(t) with an integer modulation index. The filter bank ( 10 ) has outputs for providing a plurality of decision variable values (d 1 ,d 2 ,d 3 ,d 4 ) each representing a likelihood value of a symbol, from a group of predefined symbols that are likely to be present in the continuous phase modulated signal S(t). The filter bank 10 has filter units ( 12,14,16,18 ) each having an impulse response determined by a complex main pulse containing a majority of signal energy of one of the predefined symbols that is likely to be in the continuous phase modulated signal S(t). |
