It is capable of benefiting from both pulse shaping technique and guard interval. 本文提出一种新的正交频分复用(OFDM)调制方案,结合了两种OFDM系统的特点,既利用了脉冲成形技术的优势,又能采用保护间隔。 更多例句>> 补充资料:个别劳动时间与社会必要劳动时间 两种互相联系的决定商品价值量的劳动时间。个别劳动...
p/ pCommon to all DMT/OFDM systems is a large peak-to-average ratio (PAR), which can lead to low power efficiency and nonlinear distortion. Tone reservation uses unused or reserved tones to design a peak-canceling signal to lower the PAR of a transmit block. In DMT ADSL systems, the ...

The useful information about the different diseases affecting the brain especially epilepsy are given by the frequency and energy content of this signal. As the recordings made from the EEG are quite large and difficult to process, Power Spectral Density (PSD) is employed here to reduce the ...
According to the periodic characteristic of the echo signal of the ultrasonic inner inspection on pipeline corrosion, the application of power spectrum estimation to digital ultrasonic thickness measurement has been researched. 管道腐蚀内检测中超声回波信号具有周期性特点,功率谱估计是重要的数据处理方法之一...
