说明： 一种未知信源数的高分辨DOA 估计算法：众多性能优良的超分辨波达方向(DOA)估计算法通常需要预先判定信源数目，然而，现有的信源数估计
算法在有限采样快拍条件下，估计性能随着信噪比的降低而下降，错误概率也相应增加，最终导致DOA 估计失败。
该文提出一种超分辨的DOA 估计算法，此算法不需要预判信源个数和进行特征值分解，同时在时变环境中，针对
快拍数较少的情况下，依然保持较高的角度分辨能力，可以被认为是综合了Capon 法和MUSIC 法的优点。(Algorithm on High Resolution DOA Estimation
without Sources Number：Many of the super resolution DOA(Direction-Of-Arrival) estimation algorithms presume the number of
signal sources. Since the sample snapshot is limited, however, the available algorithms on source number estimation
may fail at lower SNR. In this paper, a novel algorithm for high resolution DOA estimation is proposed, which not
only skips sources number estimation and EVD, but also behaves satisfactorily with a few snapshot, it may be
viewed as a combination of merit of conventional Capon and MUSIC method.)

Digital-baseband-system
数字基带系统将数字信号从时域上看时数字滚降，需要画出滚降前后的波形展示出来。频域上带宽变化了。输入滤波器之前的波形与采样判决之后的波形。采样判决前的频谱。
采样判决后的码型。
2、眼图（采样判决之前的眼图）（信噪比大眼图清晰）
3、误码曲线，（横坐标时信噪比，纵坐标时误码率）
4、Arfa变化对误码特性的影响，变好还是变差(变好)，眼图清晰度变化（清晰），传递函数的带宽的变化。（带宽越大）(1.Digital baseband system point of view the digital signal from the time domain when the number of roll-off, you need to draw the waveform displayed before and after the roll-out. The frequency domain, the bandwidth change. Input filter and sample ruling before the wave after wave. Sample pre-judgment spectrum.
Sampling pattern after the verdict.
2, the eye diagram (eye before sampling decision) (SNR big eye clear)
3, the error curve (abscissa when the signal to noise ratio, bit error rate when the vertical axis)
4, Arfa impact of change on BER performance, get better or worse (getting better), change of eye-definition (clarity), the transfer function of the bandwidth changes. (The greater the bandwidth))
