العنوان: (EN) Method of reducing adjacent channel interference and relay equipment
(ZH) 一种减少邻频干扰的方法及中继设备
الملخص: front page image
(EN) The invention discloses a method of reducing adjacent channel interference. The method comprises the step that a receiver acquires first analog signals from the radio frequency front of an emitter. The first analog signals are signals emitted outwards by the emitter. The signals emitted outwards by the emitter form self-interference signals on the antenna of the receiver. The method further comprises the step of performing analog-to-digital conversion on the first analog signals to acquire first digital signals. The receiver receives second analog signals. The second analog signals include useful signals and self-interference signals. The method also comprises the steps of performing analog-to-digital conversion on the second analog signals to acquire second digital signals; and performing digital cancellation on the second digital signals and the first digital signals to acquire useful digital signals in the second digital signals. The adjacent channel interference of signal emission on signal receiving is reduced through a signal processing means. The installing distance between transmitting and receiving antennas is not required to be increased. Meanwhile, a backhaul link and an access link can be configured into adjacent frequency bands. The configuring flexibility of the backhaul link and the access link is further enhanced.
(ZH) 本发明公开了一种减少邻频干扰的方法,包括:接收机从发射机的射频前端获取第一模拟信号,其中,第一模拟信号为发射机向外发射的信号,发射机向外发射的信号在接收机的天线处形成自干扰信号;将第一模拟信号进行模数转换,获得第一数字信号;接收机接收第二模拟信号,第二模拟信号包含有用信号与自干扰信号;将第二模拟信号进行模数转换,获得第二数字信号;将第二数字信号与第一数字信号进行数字对消,获得第二数字信号中的有用数字信号。本发明通过信号处理的方式减少信号发射对信号接收的邻频干扰,无需增大收发天线之间的安装距离,而且可以将回程链路和接入链路配置成相邻频带,提高回程链路和接入链路配置的灵活性。
