    • Disclosed herewith is a broadband wireless repeater for a mobile communication system. The broadband wireless repeater generally includes a transmission stage and a receiving stage. The transmission stage includes an RF switch for establishing a frequency path, an Intermediate Frequency delay unit for applying delay to IFs and bypassing the IF delay, a frequency up conversion modulator, an amplifier, a filter unit for eliminating undesired band signals, and a transmitting side antenna. The receiving stage includes an array antenna, a bandpass filter unit for eliminating undesired band signals, an amplifier, a phase shifter for controlling phases of channels, a frequency down conversion modulator, a phase comparison unit, a gain comparison unit, a vector value optimizer for decreasing errors of the main signals with a maximum output, and a synthesizing module for detecting and storing output levels of the channels.
    • 本文公开了一种用于移动通信系统的宽带无线中继器。 宽带无线中继器通常包括传输级和接收级。 传输级包括用于建立频率路径的RF开关,用于向IF施加延迟并绕过IF延迟的中频延迟单元,升频转换调制器,放大器,用于消除不期望的频带信号的滤波器单元,以及发送 侧天线。 接收级包括阵列天线,用于消除不需要的频带信号的带通滤波器单元,放大器,用于控制信道相位的移相器,降频转换调制器,相位比较单元,增益比较单元,向量值优化器 用于减少具有最大输出的主信号的误差,以及用于检测和存储信道的输出电平的合成模块。
