spread angle meaning in Chinese

扩散角
散布角

Furthermore , the mean algorithm is not sensitive to the spread angle and has a better performance
此外，均值法对分布角不敏感，且性能较优。
Simulation results demonstrate that when snr is high and spread angle is not big , the central frequency algorithm and the median algorithm are almost identical ; while when snr is low , the median algorithm outperforms the central frequency
仿真结果表明，在高信噪比和分布角不大时，中频法和中值法的性能几利相同；但在低信噪比时，中值法优于中频法。
In the second chapter , a wideband mimo channel model with multiple - tap was integrated according to the angle of departure of the transmitting signal and its spread angle , the angle of arrival of the receiving signal and its spread angle , power azimuth spectra , doppler spectrum and the geometric construction of antenna array both sides of transmit and receive , on the basis of full research on the theories of space - time channel model proposed in the recent literature
第二章在对最近文献中提出的一些空时信道模型理论进行详细研究的基础上，根据发射信号的离开角及其扩展角、接收信号的到达角及其扩展角、功率方位谱、多普勒谱和收发两端天线的拓扑结构，综合了一个多抽头的宽带mimo信道模型。
