description The invention provides a distributed beam forming method applied under a time asynchronous environment. The distributed beam forming method is mainly used for solving the problem of influence to system performance of same frequency interference and inter-symbol interference brought by the condition that the time of receiving a signal by the user is asynchronous. The method uses approximation to piecewise linear function, a convex optimization theory, user acceptance control and a weight factor iteration mechanism to form quasi-optimal distributed transmitting beams. The method of the invention is applied to a distributed antenna system, and could realize reliable united multi-user transmitting beam forming design under the time asynchronous condition of the received signal. Simultaneously, the method of the invention effectively ensures QoS requirement of the user and reduces the return link load of the system.
