CNN demodulation model with cascade parallel crossing for CPM signals
《The Journal of China Universities of Posts and Telecommunications》2024年第3期30-42,共13页Yang Jiachen Duan Ruifeng Li Chengju 
Supported by the Beijing Natural Science Foundation (L202003)。
The continuous phase modulation(CPM)technique is widely used in range telemetry due to its high spectral efficiency and power efficiency.However,the demodulation performance of the traditional maximum likelihood seque...

Low sampling rate technique based frequency-domain random demodulation for broadband digital predistortion
《The Journal of China Universities of Posts and Telecommunications》2016年第6期47-52,共6页Zhao Jingmei Liu Yuan'an Yu Cuiping Yu Jianguo 
supported by the National Basic Research Program of China (2014CB339900);the National Hi-Tech Research and Development Program of China (2015AA016801);the National Natural Science Foundation of China (61327806)
This paper proposes a combination technique of the frequency-domain random demodulation（FRD） and the broadband digital predistorter（DPD）. This technique can linearize the power amplifiers（PAs） at a low sampling ...
