    • A method for operating a transceiver includes generating, by the transceiver, a first signal that includes an estimate of an interference signal leaked from a transmit path to a receive path of the transceiver. Generating the first signal includes obtaining a baseband transmit signal that includes a baseband of a transmit signal transmitted via the transmit path. Generating the first signal also includes calculating a harmonic phase that includes a phase of a harmonic of the baseband transmit signal. Generating the first signal also includes estimating a phase shift in accordance with an envelope of the baseband transmit signal. Generating the first signal also includes determining a phase of the first signal in accordance with the estimated phase shift and the calculated harmonic phase such that interference of a receive signal received via the receive path is reduced according to the first signal.
    • 用于操作收发器的方法包括由收发器生成包括从发送路径泄漏到收发器的接收路径的干扰信号的估计的第一信号。 生成第一信号包括获得包括经由发送路径发送的发送信号的基带的基带发送信号。 产生第一信号还包括计算包括基带发射信号的谐波相位的谐波相位。 生成第一信号还包括根据基带发送信号的包络估计相移。 生成第一信号还包括根据所估计的相移和所计算的谐波相位来确定第一信号的相位,使得经由接收路径接收的接收信号的干扰根据第一信号被减小。

    • Phase shift key modulators (100, 500, 1000, 1400, 1700) are provided in which a multiphase signal source (108, 1402, 1406-1412,1702) is used to generate a plurality of phases of a carrier signal. A selector (110) is used to select one phase or a sequence of phases of the carrier signal to represent each bit pattern that is received from a binary data source (102, 1422). The multiphase signal source preferably comprises a multiphase oscillator that includes a phase locked ring of variable propagation delay inverters (202). Preferably, a phase sequencer (502) is used to select a monotonic sequence of phases to represent each bit pattern. Preferably two phase selectors (110, 1004) are used to simultaneously select two phases of carrier signal, and a phase interpolator (1106) is used to generate a sequence of phases from the two phases selected by the two phase selectors (110, 1004).
