Characteristics Analysis of Postdemodulation Multipass Signal Combining for Mobile Communication

This paper computer simulation through observes the SNR related formulas of multipass postdemodulation multipass signal combining method in case of the delay demodulation and frequency demodulation. It shows the practical configuration for the postdemodulation multipass signal combining receiver. The defined SNR degradation characteristics after multipass combining from the formulated results shows that the practical postdemodulation multipass signal combining structure is reasonable without measuring the input SNR of each multipass to obtain the maximum SNR. Also, it is verified through computer simulation results through practical configuration of delay demodulation and frequency demodulation by postdemodulation multipass signal combining method.
