Although the additional frequency diversity gain can be attained, by using efficient detection techniques, the performance of OFDM-CDM system is better than that of conventional OFDM.

CDM系统虽然获得了频率分集增益，但是，它必须通过有效的检测技术才能使其性能较之OFDM系统有所改善。

The main effect of these additional observations is a 100-point increase in the frequency count for each response alternative.

这些额外调查对象的主要影响是，使得每个回答情形的频率计数增加了 100 点。

The best part is, applying different levels of OAM twist to SAM-based transmissions theoretically allows an infinite number of streams per signal, meaning seriously increased bandwidth without the need for additional frequency.

In the DOJ's opinion, an incumbent carrier would need to demonstrate both compelling evidence of capacity constraints and an efficient use of its current licenses in order to gain additional lower frequency spectrum.

Additional applications will likely include lasers, radio frequency weapons and particle beam weapons.
