    • In one embodiment, the present invention includes a method for determining when a step change occurs to a control value for a numerically controlled oscillator (NCO) providing a mixing signal, mixing the mixing signal with an input radio frequency (RF) signal to obtain an intermediate frequency (IF) signal and demodulating the IF signal into a demodulated signal, generating a correction value based on the step change, and applying the correction value to the demodulated signal. Other embodiments may be used to cancel other undesired signal portions, such as impulse spikes generated from the NCO change.
    • 在一个实施例中,本发明包括一种用于确定何时发生阶跃改变以提供混合信号的数控振荡器(NCO)的控制值,将混合信号与输入射频(RF)信号混合以获得 中频(IF)信号并将IF信号解调为解调信号,基于该阶跃变化产生校正值,并将该校正值应用于解调信号。 可以使用其他实施例来消除其他不期望的信号部分,例如从NCO变化产生的脉冲尖峰。

    • A method and apparatus for adjusting the delay of a first data stream relative to a second data stream is disclosed. An apparatus receives first and second data streams having identical content. A timing difference between the first and second data streams is estimated. At least the leading one of the data streams is applied to a sample rate converter. The sample rate converter is configured to receive a data stream at an input sampling rate and to output the data stream at an output sampling rate. Based on the estimated timing difference, delay is applied to the leading one of the data streams by changing the sampling rate of the sampling rate converter. The output sampling rate of the sampling rate converter may be adjusted until both data streams are aligned in time.
    • 公开了一种用于调整第一数据流相对于第二数据流的延迟的方法和装置。 一种装置接收具有相同内容的第一和第二数据流。 估计第一和第二数据流之间的定时差。 至少将前导数据流应用于采样率转换器。 采样率转换器被配置为以输入采样率接收数据流,并以输出采样率输出数据流。 基于估计的定时差,通过改变采样率转换器的采样率,将延迟应用于数据流中的一个。 可以调整采样率转换器的输出采样率,直到两个数据流在时间上对准。

    • A method performed by a receiver is provided. The method includes generating an RDS/RBDS candidate codeword from a set of RDS/RBDS symbols where the RDS/RBDS candidate codeword has a subset of RDS/RBDS values that differs from corresponding subsets of RDS/RBDS values in all other possible RDS/RBDS codewords and determining whether the RDS/RBDS candidate codeword meets an acceptance criterion by comparing a first subset of reliability values determined from the set of RDS/RBDS symbols and having signs that differ from corresponding signs in the subset of RDS/RBDS values with a second subset of reliability values determined from the set of RDS/RBDS symbols and mutually exclusive with the first subset of the reliability values. A first number of values in the first and the second subsets of reliability values is less than a second number of values in the RDS/RBDS candidate codeword.
    • 提供了一种由接收机执行的方法。 该方法包括从一组RDS / RBDS符号生成RDS / RBDS候选码字,其中RDS / RBDS候选码字具有在所有其它可能的RDS / RBDS中与RDS / RBDS值的相应子集不同的RDS / RBDS值的子集 码字,并且通过比较从该组RDS / RBDS符号确定的具有不同于RDS / RBDS值子集中的对应符号的符号的第一可靠性子集,确定RDS / RBDS候选码字是否满足接受标准 从RDS / RBDS符号集确定并与可靠性值的第一子集相互排斥的可靠性值子集。 第一和第二可靠性子集中的第一数量的值小于RDS / RBDS候选码字中的第二数量的值。
