    • A method for forming signals at a transceiver having at least two transmit and receive chains, the method comprising the steps of: (a) determining the phase difference and relative amplitude of signals from a set comprising 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.

    • To limit a combined signal, the method comprises multiplying an information signal intended for each subscriber terminal by a spreading code and a weighting coefficient, which is proportional to the power of the transmission directed to the subscriber terminal. The method comprises setting a threshold value, dividing the combined signal into blocks, comparing the values of each block with the set threshold value and if the threshold value is exceeded, decorrelating the block where the threshold value was exceeded and a pre-determined number of channelization codes, which have a pre-determined spreading factor. The decorrelation result is normalized to determine first weighting coefficients. The method also comprises comparing each combination of a first weighting coefficient and a related channelization code with the set objectives and determining second weighting coefficients for the downlink transmissions selected as a result of the comparison. The examined block is re-formed using combinations of the channelization codes and the weighting coefficients that were determined.
    • 为了限制组合信号,该方法包括将针对每个用户终端的信息信号乘以扩展码和与指向用户终端的传输功率成比例的加权系数。 该方法包括设置阈值,将组合信号划分为块,将每个块的值与设定的阈值进行比较,并且如果超过阈值,则将超过阈值的块解除关联,并将预定数量的 信道化码,其具有预定的扩频因子。 将去相关结果归一化以确定第一加权系数。 该方法还包括将第一加权系数和相关信道化码的每个组合与所设定的目标进行比较,并确定作为比较结果选择的下行链路传输的第二加权系数。 使用确定的信道化码和加权系数的组合重新形成被检查的块。
