摘要：
A method apparatus are provided for mitigating spectral lines in a wireless signal. First a code word is generated that is made up of a plurality of binary or ternary encoded pulses. Then a plurality of code-word-modulated wavelets are generated in response to the code word. These wavelets can be Gaussian monopulses, repeated cycles of a sine wave, or other shaped impulse signals. The plurality of code-word-modulated wavelets are then modulated with a bit of transmit data to form a plurality of data-modulated wavelets. This modulation serves to whiten the signals since the transmit data is effectively random. Finally, the plurality of data-modulated wavelets are transmitted to a remote device.
摘要（中）：
提供了一种用于减轻无线信号中的频谱线的方法装置。 首先，生成由多个二进制或三进制编码脉冲组成的码字。 然后响应于码字产生多个码字调制小波。 这些小波可以是高斯单脉冲，正弦波的重复周期或其他成形脉冲信号。 然后用一些发送数据调制多个码字调制小波，以形成多个数据调制小波。 该调制用于使信号变白，因为发送数据是有效的随机的。 最后，将多个数据调制小波发送到远程设备。
