Abstract
A distribution method of multi basic midamble includes following step A. determining the number of channelizing code of a cell or sector (s101); B. configuring more than one of basic midamble to the cell or sector (s102); C. generating midamble which is no less than said channelizing code using said more than one of basic midamble (s103); D. configuring said midamble to make each channelizing code correspond to different midamble respectively (s104). The invention can configure multi basic midamble code in a cell or sector to make midamble correspond to all of adoptable spread spectrum code one-to-one, can improve the accuracy of joint detection remarkably and efficiently, and can change the service speed more securely. Furthermore, acquiring channelizing impulse response and corresponding spread spectrum code using the exact corresponding of midamble and spread spectrum code can acquire user original signal exactly. The invention also includes a joint detection method.
