Sentence examples for frequency efficiencies from inspiring English sources

The lookup table defines 35 levels of frequency efficiencies (bps/Hz) according to the various modulation schemes, i.e., QPSK, 16 QAM, and 64 QAM, and the coding rates under the considerations of 1 2 MIMO, channel prediction, and HARQ.

Although the adoption of more efficient transmission technologies, such as OFDM, MIMO, and Turbo coding etc., the frequency efficiency has been improved greatly, the cost of data transmission in wireless telecommunication is still extremely high due to more bandwidth requirement, which is seen as the most precious resource in wireless telecommunication.

The impact of the time efficiency dominates the impact of the frequency efficiency.

Although the current form of a WRNS works adequately, it has a significant limitation in terms of the frequency efficiency.

Despite the problem of frequency scarcity, the goal of the current deployment of a WRNS is not aligned with the frequency efficiency.

A key technology to solve this problem is multi-antenna techniques, which can enhance the frequency efficiency and link reliability drastically.

In contrast, MU-MIMO makes it possible to multiplex users in the spatial domain so that higher frequency efficiency can be expected even when using simple users.

However, the simultaneous transmission which prevent the loss of frequency efficiency is possible for BRUS and ICRS schemes for some cases.

The frequency efficiency characterizes the spectral containment of each waveform and is defined as: r_{f} = frac{N'}{N'+N_{text{guard}}} (12).

The scheduler first calls the channel module to obtain information on the modulation and coding scheme (MCS) and achievable frequency efficiency (bps/Hz) for each PRB.

For periodic packet scheduling based on PF scheduler which considers frequency efficiency of each sub-band, the simulator basically adopts the periodic sub-band CQI report.
