Along with the development of modern radar technology, the radar signal system is more and more complicated. This makes the description way of the existing radar signal feature cannot effectively express and analysis it's characteristic. Therefore, in this kind of situation, a description method of radar...
Compensation for the demodulated phase errors caused by sampling frequency offset in OFDM systems
Yujie Xiong, Xiaofei Zhang, Yi Zhang
OFDM has been successfully adopted in Digital video broadcasting-terrestrial (DVB-T) due to its excellent spectral efficiency and inherent resistance to multipath effect. However, OFDM is a multi-carrier transmission technique and sampling frequency offset (SFO) always exists in OFDM systems. It must...
A Linear Time Algorithm for Cubic Subgraph of Halin Graphs
Dingjun Lou, Junfu Liu
In this paper, we design a linear time algorithm to determine whether a Halin graph H has a cubic subgraph H*. If H has, then the algorithm finds a cubic subgraph H* in H; otherwise the algorithm answers “No”
A reflective TWTA predistortion linearizer for Ka-band application
Yongfei Wang, Dongfang Zhou, Qing Hu, Ying Zhao
A predistortion linearizer used for Ka-band travelling wave tube amplifiers (TWTAs) was proposed. Based on analysis of nonlinear transfer characteristics of TWTA using a power series, the inverse nonlinear distortion characteristics of predistorter which was also the model of predistortion linearizer...
