Assuming that linguistic specifications and information planning contribute to different levels of prosodic organization that cumulatively constitute output prosody, quantitative analysis of respective contributions can be derived through normalization procedures that remove levels of interactions involved. The current study attempts to account for how Τ2 prosody departs from the Τ1 norm in the two...
In this paper, a simplified online coefficients updating technique is proposed to realize real-time tuning of digital predistortion (DPD) for RF power amplifiers (PAs), particularly focusing on wideband and concurrent multi-band scenarios. It is achieved by equally weighting the memory terms in conventional DPD models that leads to a significant reduction of numerical calculation complexity in the...
When the use of mobile devices is soaring, the demand for higher data rates over wireless networks is continuously increasing. To meet the demand, one of the obvious solutions is to increase the bandwidth of the transmission frequency band. However, no matter how much you are willing to pay for the spectrum, you can no longer easily obtain a large contiguous bandwidth because most spectrum bands have...
In this paper, a novel digital post-correction method with real-time FPGA implementation is proposed to correct the distortion generated by high-speed analog-to-digital converters (ADCs). It is achieved by simplifying the dynamic deviation reduction-based Volterra series to form an accurate model to effectively compensate both static nonlinearities and memory effects. Both post-correction model generation...
China is one of largest cotton-producing countries in the word. Cotton stalk production (dry mass)in China is above 900 million tons per year. The conversion of these materials by thermochemical processes like pyrolysis can significantly and immediately reduce the mass and volume of wastes, allowing for energy recovery. In this paper, the pyrolysis characteristics and kinetics of cotton stalk were...
