    • A cellular radio telecommunication system comprises a basestation having at least two antennas (107, 114). Each antenna is arranged to transmit a downlink signal to one or more mobile subscriber units. The downlink signal is transmitted from each antenna (107, 114) having a mutual time delay and phase difference, the phase difference changing from time to time. Because of the mutual phase differences, if the signals received at a mobile station are mutually in anti-phase during one time slot of the downlink signal, there is a very low probability that they will also be in anti-phase at the corresponding time slot in the next several frames.
    • 蜂窝无线电通信系统包括具有至少两个天线(107,114)的基站。 每个天线被安排为向一个或多个移动用户单元发送下行链路信号。 下行链路信号从具有相互时间延迟和相位差的每个天线(107,114)发送,相位差随时间变化。 由于互相的相位差,如果在下行链路信号的一个时隙期间移动台接收的信号相互反相,则它们在相应的时隙也将反相的可能性很低 在接下来的几个帧中。
