摘要：The present invention discloses a method and a system for spread frequency spectrum. The method comprises : after demodulating and dispreading by receive end the high frequency modulated signal sending by mobile station or base station, performing the channel estimation to the fade channel by the judgement fedd back channel estimation loop. Using the method of the present invention can save the transmit power of the base station or the mobile station, and can effectively overcome the influence of the signal amplitude and phase, can satisfy the application of high rate transform and high speed moving environment, can apply to the forward (base station to mobile station) and reverse (mobile station to base station) channels without any changing and can be easily performed.
