    • The application discloses embodiments of methods and/or systems for compensating a transmission carrier leakage of an up-conversion mixer, a tranceiving circuit or apparatus embodying the same. One embodiment of a method can include detecting an I channel DC offset DCI0 and a Q channel DC offset DCQ0 generated by a reception carrier leakage from an output of a down-conversion mixer, detecting an I channel DC offset DCI and a Q channel DC offset DCQ from the output of the down-conversion mixer while varying a compensation parameter being inputted to an up-conversion mixer that has its output coupled to an input of the down-conversion mixer to determine the compensation parameter that can reduce or minimize a transmission carrier leakage. A combination of a transmission baseband signal and the determined compensation parameter can be transmitted using the up-conversion mixer and an antenna to compensate for the transmission carrier leakage.
    • 本申请公开了用于补偿上变频混频器,引入电路或体现其的转换电路或设备的传输载波泄漏的方法和/或系统的实施例。 方法的一个实施例可以包括从下行链路的输出检测由接收载波泄漏产生的I信道DC偏移DCI 0和Q信道DC偏移DCQ <0> 转换混频器,从下转换混频器的输出端检测I信道DC偏移DCI和Q信道DC偏移DCQ,同时改变输入到上变频混频器的补偿参数,该上变频混频器的输出耦合到下变频混频器的输入 转换混频器来确定可以减少或最小化传输载波泄漏的补偿参数。 传输基带信号和所确定的补偿参数的组合可以使用上变频混频器和天线来传输,以补偿传输载波泄漏。
