This paper discusses the acquisition of BOC signals in multipath fading channels.It first compares the acquisition performances in various channels using the currently superior acquisition algorithm on the basis of the models of multipath fading channels.Then it analyzes the impacts of the channels on the acquisition performances in connection with Rice factor K

multipath routing number Land multipath delay.Theoretical analysis and simulation results show that the larger the Rice factor K

the larger the acquisition function peak value and the better the acquisition performance

while the smaller the multipath routing number L

the less the side peaks and the better the acquisition performance.
