In this thesis, we adopt the bandwidth-efficient OFDM system, which can adjust efficiency of bandwidth usage.

在本论文中，我们采用高频宽效率的正交分频多工调变系统。

For the most part, you don't want to optimize for speed, or bandwidth utilization, or any other type of efficiency — but for something more nebulous: user satisfaction.

在大多数情况下，优化的目标并不是速度、带宽利用率或者其他效率指标，而是更模糊的目标：用户满意度。

At high input impedances, in practice both efficiency and bandwidth of a transformer will reduce.

实际上高输入阻抗的变压器，它们的效率和频带宽度都会下降。

youdao

Things like the number of computer instructions per clock cycle, the bandwidth of the RAM bus, and the overall efficiency of the architecture are at least as important as the raw clock speed at which a processor runs.
