doa_signal
低信噪比条件下的高分辨DOA估计算法,提出一种基于多级维纳滤波器(MSWF)的信号波达方向(DOA)估计算法。通过测试信号子空间的估计值与噪声子空间的正交性实
现 DOA粗估计，通过测试MSWF 分解的互相关函数实现信号 DOA 的精估计。仿真实验表明，在低信噪比条件下，该算法比已有的子空
间类算法有更好的分辨率和误差性能。(Put forward a kind of multistage Wiener filter (MSWF) based on the signal direction of arrival (DOA) estimation algorithm. By testing the orthogonality between the estimated values of the signal subspace and the noise subspace
Now DOA coarse estimation, by testing the MSWF decomposition of the cross-correlation function to achieve accurate estimation of signal DOA. Simulation results show that the proposed algorithm is more efficient than the existing subspace in low SNR conditions
The inter class algorithm has better resolution and error performance.)

通信编码
说明： lbc_example：未编码的BPSK调制的性能（理论计算与仿真）、重复码硬判决的性能
lbc_example_SD： 未编码的BPSK调制的性能（理论计算）、重复码硬判决的性能、重复码软判决的性能
lbc_example_SD_EbNo：lbc_example_SD中的性能，并且进一步考虑了码率不同时，对于信道的SNR值进行归一化，以Eb/No = SNR/(2*R)为横坐标时的比较结果
lbc_example_Hamming_EbNo：汉明码，硬判决译码的性能(Lbc_example: Performance of uncoded BPSK modulation (theoretical calculation and simulation), performance of duplicate code hard decision
Lbc_example_SD: Performance of uncoded BPSK modulation (theoretical calculation), performance of hard decision of duplicate code, performance of soft decision of duplicate code
The performance of lbc_example_SD_EbNo: lbc_example_SD is considered, and the SNR value of channel is normalized when the bit rate is different. The comparison results are obtained when Eb/No = SNR/(2*R) is the abscissa coordinate.
