carrier-modulation
多载波调制(Multicarrier Modulation)采用了多个载波信号。它把数据流分解为若干个子数据流,从而使子数据流具有低得多的传输比特速率,利用这些数据分别去调制若干个载波。所以,在多载波调制信道中,数据传输速率相对较低,码元周期加长,只要时延扩展与码元周期相比小于一定的比值,就不会造成码间干扰。因而多载波调制对于信道的时间弥散性不敏感。多载波调制可以通过多种技术途径来实现,如多音实现(Multitone Realization)、正交多载波调制(OFDM)、MC-CDMA和编码MCM(Coded MCM)。其中,OFDM可以抵抗多径干扰,是当前研究的一个热点。(Multi carrier modulation (Multicarrier Modulation) uses multiple carrier signal. It decomposes a data stream into a plurality of sub data stream, so that the sub data stream transmission bit rate is much lower, respectively to a plurality of carrier modulation using these data. )

Wind turbine generators (WTGs) are usually
equipped with mechanical sensors to measure wind speed and
turbine shaft rotating speed for system monitoring, control, and
protection. The use of these sensors increases the cost and
hardware complexity and reduces the reliability of the WTG
system. This paper proposes a novel real-time speed estimation
algorithm for wind turbines equipped with doubly-fed induction
generators (DFIGs).
