When UHF broadcasting came along, empty “guard bands” were added to each channel for the same reason.
而当超高频广播出现时，每个频道基于同样的理由，也加上了空闲的“保护频带”。

To overcome the leakage of CIR, the frequency guard bands are reduced by using the polynomial cancellation coding(PCC) training symbols.
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。
A frequency translation circuit (172-188) abuts the multiple channel bandpass filtered analogue signals in the frequency domain without any guard bands between adjacent channel signals.
频率平移电路(172 ~ 188)使得经过带通滤波的若干多通道模拟信号在频域中接邻，而在相邻通道信号之间没有任何保护频带。
This method is less computationally complex than other similar approaches, and avoids spectrum inversions, while including analyses of the guard-bands.
与其他方法相比，该方法计算复杂度较低，能够避免频谱倒置的情况，并且可以兼顾频谱间的保护间隔。
