Abstract :
Differential detection of continuous phase modulation suffers from significant intersymbol interference. To improve the bit error rate performance, multi-branch fractional multi-bit differential detection with decision feedback is proposed. By introducing decision feedback in multi-bit differential detected signals, severe intersymbol interference can be removed. Simulation results show that the proposed structure can provide great improvement compared with MFMDD without decision feedback, and the best performance is achieved which is very near to the performance of the coherent detection.
