Abstract :
A suboptimum noncoherent detector for partial response CPM (continuous phase modulation) is studied. The number of filters in the filter bank is reduced by using a limited signal space in the CPM detector. It is found that the number of dimensions in the mismatched detector can be considerably reduced. For a quaternary 2RC scheme with h=1/3, the number of filters is reduced from 32 to eight with a loss of about 0.5 dB in error performance. SAN(B), a limited tree search algorithm, is used for the symbol decision
