    • A process which adjusts the transmission and reception chains of the paths formed by a base station of a system for radio communication between mobiles which after calibration of the antenna base adjusts the reception chains relating to each path by distributing a first specified adjustment signal synchronously over each of the reception chains and calculating an equalization filter which inverts the transfer functions related to each reception chain. The process next adjusts the transmission chains related to each path by distributing a second specified adjustment signal synchronously over each of the transmission chains, by extracting from each of the paths a part of a transmission signal before the transmission signal is sent to the antenna base so as to re-inject that part of the transmission signal into the reception chains, and by calculating an equalization filter which inverts the transfer functions related to each transmission chain. Finally, the process receives via the equalization filters previously calculated for the reception chains reception signals originating from the antenna base, or transmits via the equalization filters previously calculated for the transmission chains the transmission signals originating from the multipath transmission/reception device.
    • 调整由用于移动台之间的无线电通信的系统的基站形成的路径的发送和接收链的过程,其在天线基准校准之后通过在每个路径上同步地分配第一指定的调整信号来调整与每个路径相关的接收链 并计算均衡滤波器,该均衡滤波器反转与每个接收链相关的传递函数。 该过程接下来通过在每个发送链上同步地分配第二指定调整信号,通过在发送信号被发送到天线基底之前从发送信号的一部分中提取每个路径来调整与每个路径相关的发送链,从而 将发送信号的该部分重新注入到接收链中,并且通过计算反转与每个传输链相关的传递函数的均衡滤波器。 最后,该处理经由先前针对从天线基站发送的接收链接收信号计算的均衡滤波器接收,或者经由先前为传输链路计算的均衡滤波器发送来自多径发送/接收装置的发送信号。
