    • A method (700) and apparatus (200) mitigates spurious transmissions. An offset local oscillator signal (266) is generated that is at a frequency that is offset from a nominal transmit channel carrier frequency by a spurious mitigation offset (203). An information signal (206) is generated that comprises a series of modulation symbols and has a transmission bandwidth (212) at baseband. A configured offset information signal (226) is generated from the information signal, wherein the spectrum of the configured offset information signal is offset from DC by a channel configuration offset (218), and is further offset by a negative of the spurious mitigation offset (202). The offset local oscillator signal and the configured offset information signal are combined using a mixing technique. The spurious mitigation offset is zero when a spurious condition does not exist and is non-zero when the spurious condition does exist.
    • 方法(700)和装置(200)减轻杂散传输。 产生偏移本地振荡器信号(266),该偏移本地振荡器信号处于与标称发射信道载波频率偏移假消除偏移(203)的频率处。 产生包括一系列调制符号并且在基带处具有传输带宽(212)的信息信号(206)。 从信息信号生成配置的偏移信息信号(226),其中配置的偏移信息信号的频谱通过信道配置偏移(218)从DC偏移,并进一步被寄生减轻偏移的负值 202)。 偏移本地振荡器信号和配置的偏移信息信号使用混合技术进行组合。 当杂散条件不存在时,杂散减轻偏移为零,当杂散条件确实存在时,杂散缓解偏移为零。
