您要查找的是不是:
- Theoretical analysis indicates the sequence of coefficient module of Haar wavelet transform has discrete spectral lines in the power spectrum. 通过对此单极性脉冲序列的功率谱分析可知,在基带信号码元速率的整数倍处存在离散谱线,检测这些离散谱线即实现了信号码元速率的估计。
- Whatever the value of the mark rate of information code is,the mark rate of translated code format is always 1/2. Because the mark rate is 1/2,there are not discrete spectral lines in power spectrum. Therefore phase jitter does not exist. 无论信息码传号率为何值,经码型变换后,该种码型传号率均为1/2,以致离散谱线为0,故不会产生相位抖动。
