Method and device for space-time diversity transmitting based on intelligent autema CDMA system

A space diversity emitting method for CDMA system, based on intelligent antenna CDMA system is to utilize the weighted coefficient corresponding to the intelligent antenna different multipath separately to get multiset emitting signals of different antenna arrays to emit the said signal via RE channel and antenna according to certain time interval. A space-time diversity emitting device based on the above mentioned method includes: antenna array and related RF channel, intelligent antenna system, RAKE receiver receiving an emitting conversion system and time-space diversity emitting device, changing the present state of only one path for signal emitting, solving the problem of not sharp PAKE merge gain at the receiving end or possible breaking.
