摘要

The effect of system frame synchronization in a frequency-hopped (FH) spread-spectrum digital mobile radio communication system is evaluated. A novel mathematical approach is used for modeling the FH-BFSK mobile radio system in the presence of Rician fading, multiuser interference and Gaussian white noise. Besides the synchronization error between users, the influence of propagation conditions in different types of region, and the effect of coding are considered. The results show that the multiuser interference is a serious problem which limits the system's capacity. Performance degradation increases quickly with the frame synchronization error. A good frame is maintained to minimize the bit error rate (BER). System performance can be improved by increasing the signal-to-noise ratio, only where there is a good system frame synchronization.
