1.The invention discloses a method for modulating carrier frequency and a base station.本发明公开了一种载频调配的方法与基站。

2.Hard-handoff is the only way for those different carriers to achieve handoff.对于不同载频之间的切换，只能采用硬切换实现。

3.As the capacity of a single carrier gradually (insufficient), so in some urban areas operators start to add new carriers.在一些城市地区，一个载频的容量逐渐不够，开始增加新的载频。

4.The carrier frequency offset estimation algorithm and channel estimation algorithm are studied and implemented in this paper.本文对自组织网物理层的载频估计算法和信道估计算法进行了研究和实现。

5.However, due to the size of a mobile and carrier frequency constraints, multiple antennas can not be possibly implemented.然而由于移动台的尺寸和载频的限制，使多天线技术很难实现。

6.If this alarm is raised on a CTU2 radio type, a failure of one of the radio's synthesizers has occurred.如果告警是在CTU2载频出现的，则可能射频合成器产生故障。

7.Lastly, The jamming effectiveness is emphatically analyzed in the presence of bit error, bit width error and carrier frequency error.最后分析了干扰信号在存在误码、元宽度误差以及载频误差情况下的干扰效果。

8.Firstly, delay-multiply signal can detect the chip rate and the carried frequency in the frequency domain through multi-autocorrelation.首先对延时相乘信号进行多重自相关处理，在频域可以检测出信号的码片速率、载频。

9.Firstly, the proposed method converted the receiver signal to base-band waveform via estimated carrier frequency.该方法首先利用估计的载频对接收信号进行解调、低通滤波；

10.But if the Doppler frequency offset exceed the capture range of PLL, the carrier synchronization will fail.但是，一旦多普勒频移超出了锁相环的频率捕捉范围，就无法完成载频同步。
