现代无线通信要求频率综合器同时满足快速切换时间，小信道宽度和低噪声性能三方面的要求。
Modern wireless communication requires that the frequency synthesizer should have fast settling time, small channel width and low phase noise.
在分频多任务（用于模拟讯号），信道切割成次信道，每个信道具有不同的频率宽度，指定给特定的讯号。
In FDM (typically used for analog signals) the channel is subdivided into subchannels, each with a different frequency width that is assigned to a specific signal.
为了解码需要样品的宽度文件(比特数)，和采样频率(赫兹)，和本的信道数。
In order to decode the file you need the width of the samples (number of bits), and the sampling frequency (Hertz), and the number of channels present.
使用多项式相消编码（PCC）训练符号进行信道估计，利用其频谱陡降的特点减少保护边带宽度，进而降低CIR泄漏。
To overcome the leakage of CIR, the frequency guard bands are reduced by using the polynomial cancellation coding(PCC) training symbols.
