Abstract
Group delay distortion between channels is one of the most important factors which affect the BER (bit error rate) performance of DBF (digital beam forming) System. The basic principles of DBF and the concept of group delay are first introduced, and a linear group delay filter is designed based on the relationship between the minimum phase system and the cepstral coefficients. And then a multi-channel group delay distortion model for simulation in MATLAB software is established. A QPSK system is simulated in multi-channel group delay. Simulation results show that the degradation of BER performance is caused by group delay distortion, and the more serious distortion of group delay, the greater deterioration of BER performance
