Abstract
In this paper，we first explore the possibility to separatesubchip multipath components under spread spectrum communication model，through analysis multi-path propagation affection on receiver performance with transmitting un-modulated signals and modulated signals.After that the discrete output expression of cross correlation is educed.The possibility to separate subchip multipath components is approximately transferred to resolve a set of coupled equations.Finally，with assumption that the output of receiver filter is rectangular pulse and triangle pulse，respectively，the possibility to separate subchip multipath components is evaluated.Simulation results show the parameters of subchip multipath components，amplitude and phase shift，are well resolved，and the estimation errors for propagation delay are determined by sampling interval.关键词
