    • Provided is an on-channel repeater, which removes feedback signals caused due to low isolation of transmission/reception antennas and a method thereof. The on-channel repeater includes : a receiver for receiving radio frequency (RF) signals and converting them into baseband signals; a subtractor for subtracting replicas of feedback signals from the baseband signals to thereby produce signals whose feedback signals are primarily removed; a demodulator for demodulating the signals which include the remaining feedback signals; an equalizer for equalizing the demodulated signals to thereby produce equalized signals; a transmitter for modulating the equalized signals to thereby produce modulated signals, converting the modulated signals into RF signals, and transmitting the RF signals in the air; a down-converter for down-converting the RF signals into baseband signals; and a replica generator for calculating the replicas based on the baseband signals of the down- converter and the signals without feedback signals of the subtractor, and feeding back them to the subtractor.
    • 提供一种同信道中继器,其消除由于发送/接收天线的低隔离引起的反馈信号及其方法。 同频中继器包括:用于接收射频(RF)信号并将其转换成基带信号的接收机; 减法器,用于从基带信号减去反馈信号的副本,从而产生其反馈信号被主要去除的信号; 解调器,用于解调包括剩余反馈信号的信号; 均衡器,用于均衡解调的信号,从而产生均衡的信号; 用于调制均衡信号从而产生调制信号的发射机,将调制信号转换为RF信号,并在空中传送RF信号; 用于将RF信号下变频为基带信号的下变频器; 以及用于基于下变频器的基带信号和没有减法器的反馈信号的信号来计算副本的副本生成器,并将其反馈到减法器。
