Fifth problem, Pattern Simulation of inverse transform
Ⅰ, basic tasks: decision by the sampling pattern after AMI and CMI pattern sequence to recover the original digital PCM pulse code signal.
Main steps and requirements:
(1) post-judgment by the AMI code sample digital sequence to restore the original PCM pulse code signal (signal 0,1). AMI requires post-judgment sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform.
(2) post-judgment by the CMI sampling digital code sequence to restore the original PCM pulse code signal. Requirements of post-judgment CMI sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform.
Ⅱ, choose to do the task: the post-judgment by the sample type HDB3 code sequence to recover the original digital PCM pulse code signal.

a-novel-approach-to-DOA-estimation
子空间类波达方向(Direction Of Arrival,DOA)估计算法的关键在于得到高质量的信号子空间估计。该文利用矩阵伪逆的双正交性,针对源信号不相关而其本身是色信号的情况,给出了一种新颖的DOA估计算法,它不需要知道噪声统计特性。该算法利用一组空间相关矩阵的结构化信息,能稳健而精确地估计出信号子空间,从而得到DOA的精确估计。仿真实验证实了所给算法的有效性。(The key subspace DOA (Direction Of Arrival, DOA) estimation algorithm is to get a high quality signal subspace estimation. In this paper, the use of pseudo-inverse matrix dual orthogonal signals for the source itself is not related to the case and the color signal is given a novel DOA estimation algorithm, it does not need to know the statistical properties of the noise. The algorithm uses a set of structured information in spatial correlation matrix can be robust and accurately estimate signal subspace to obtain an accurate estimate of the DOA. Simulation experiments confirmed the effectiveness of the proposed algorithm.)
