频谱利用 meaning in Chinese
spectrum utilization
Examples
- Effective gain in spectrum utilization
频谱利用有效增益 - The predistortion , which aims at compensating for the nonlinear distortion caused by the power amplifier , has a good performance in eliminating the nonlinear distortion of am / am & am / pm , improving the aci and spectrum efficiency
预失真技术是针对射频功率放大器非线性而提出的一种补偿技术，可以有效消除由非线性造成的传输信号的幅度和相位失真，降低信号邻道干扰( aci ) ，提高频谱利用效率。 - Smart antenna may reduce coggege of electronic engineering of uestc , the cochannel interferences ( cci ) , enhance the user capacity and spectrum efficiency , reduces the transmit power and electromagnetic interferences , enhance the transmit efficiency , dynamically divide cells in third generation cellular
智能天线技术应用于第三代移动通信系统中具有可以减小因频率复用造成的共信道干扰( cci ) 、提高频谱利用效率及增大系统容量、减小发射功率和空间电磁干扰、增加发射效率、对小区进行动态划分等优点。 - To solve the former problem , hiarachical cellular system ( hcs ) could be applied , where macrocells cover low - teletraffic areas and serve slow calls , while microcells overlay high - teletraffic areas and serve fast calls . by this means , better spectrum efficiency can be achieved and the number of handoffs can be decreased
对于前者，采用多层蜂窝系统( hcs ) ，使得宏蜂窝覆盖低话务量地区并为快速呼叫提供服务，而微蜂窝覆盖高话务量地区并为慢速呼叫提供服务，这样既保证较高的频谱利用效率，又能有效地降低呼叫的切换次数。
