I introduce the frequency allocation between BCCH carrier frequency and TCH, signal fading arithmetic, interference theory and the adjusting thinking of dynamic power control.

介绍了BCCH载波与TCH载波的频率配置、信号衰落算法、干扰原理、动态功率控制的调节思路，以及提高网络质量，改善小区登陆与切换性能的措施。

The noise generation and filters are performed by a microprocessor for which the input time constant of CTC can be varied to control the fading rate.

噪声的产生和滤波均由单板机实现。改变单板机CT C定时器的输入时间常数，就可直接调整模拟衰落信号的衰落速率。
