该体制具有较高的频率利用率，可有效地抑制短波信道中多径时延、频率选择性衰落、人为干扰与噪声带来的不利影响。
This new scheme has the advantages of high spectrum efficiency and suppression of multipath spread, frequency selective fading, jamming and noise.
CD MA通信系统由于具有容量大、软容量、软切换、频率利用率高、抗多径衰落能力强等优点而在第三代移动通信系统(3 G)中得到广泛应用。
The advantages of CDMA communication system in 3g are large capacity, soft capacity, soft handover, higher spectral efficiency and the ability to resist the effects of multi-path fading, and so on.
动态调控器(详见下文)可以根据CPU利用率来调整cpu频率，从而有助于节省电能，而不会牺牲性能。
The dynamic governors, which I discuss later in this article, can switch between CPU frequencies based on CPU utilization to allow for power savings while not sacrificing performance.
