    • A method for forming signals at a transceiver having at least two transmit and receive chain, the method comprising the steps of: (a) determining the phase difference and relative amplitude of signals from a set cmprising a plurality of mobile stations as received through the receive chains, (b) receiving from each of at least one of the mobile stations messages indicative of the strength or quality of signals as received by the respective mobile station from the transceiver and on the basis of those messages determining a phase offset and amplitude distortion, internal to the transceiver, resulting from the differences in the instrumental properties of the receiver and transmitter chains in the transceiver; and (c) transmitting signals from each of the transmitter chains by applying to each transmitter chain amplitude weights and signal delays, selected on the basis of the determined phase offset and amplitude distortion, and received relative amplitudes and phase differences.
    • 一种用于在具有至少两个发射和接收链的收发机上形成信号的方法,所述方法包括以下步骤:(a)确定通过所述接收器接收的来自多个移动站的信号的相位差和相对幅度 链路,(b)从至少一个移动站中的每一个接收消息,指示相应移动站从收发机接收的信号的强度或质量,并且基于确定相位偏移和幅度失真的那些消息, 由收发器中的接收器和发射器链的仪器性质的差异导致的收发器内部; 并且(c)通过对每个发射机链应用基于所确定的相位偏移和幅度失真选择的振幅权重和信号延迟以及接收到的相对幅度和相位差来从每个发射机链发射信号。
