频谱效率 meaning in English
spectral efficiency
spectrum effectiveness
Examples
- Spectral efficiency of adaptive transmission in urban microcellular networks
城市微蜂窝网络中自适应传输的频谱效率 - 8psk has the potential to increase the data rate of existing gsm systems by a factor of three
与原有的gmsk调制方式相比， 8psk不但可以提高数据率，而且可以获得较高的频谱效率。 - But the spectrum efficiency of the traditional ofdm system is limited due to variance of channel parameters such as channel response and rms delay spread
但是，决定通信系统调制参数的信道响应和rms时延扩展由于物体的运动或者环境的变化而动态变化，传统的静态确定ofdm系统调制参数的方法的频谱效率不够高。 - Mimo - ofdm has been regarded as the key technology of b3g communication system because it can improve system capacity and spectrum efficiency . however , ofdm is very sensitive to frequency offset
由于能够显著改善频谱效率、提高数据传输速率和系统容量, mimo - ofdm技术被广泛认为是后三代移动通信系统( b3g )的关键技术。 - In this thesis , we compared the two acm through simulation , and analyzed their merits and flaws . then we present an optimal design scheme of average spectral efficiency in adaptive coded modulation system
本文对上述两种自适应编码调制策略做了比较,分析了各自的优缺点,并提出了一种基于平均频谱效率的自适应编码调制的优化方案。
