39316 本文对已有的四种典型提取方法(主成分分析法、最小二乘法、掩蔽法以及环境声相位估计法)进行主客观评估， This paper presents the objective comparisons and subjective evaluations on four typical extraction methods, which are Principal Component Analysis(PCA), Least-Squares(LS), Masking and Ambient Phase Estimation with a Sparsity constraint(APES).
39317 其中对比了不同方法提取成分的提取误差和通道间相关值两个客观指标，并将提取成分用于双耳渲染对音质和声像宽度进行主观测听。 Extraction performance is quantified by two objective criteria, which are Error-to-Signal Ratio(ESR) and Inter-channel Cross Coherence(ICC). And the extracted components are also used in the binaural rendering to evaluate the sound quality and the sound image width by subjective evaluation.
39318 主客观评估结果表明，提取成分越精确，在双耳渲染中可得到越好的音质;提取的环境声的通道间去相关性越强，在双耳渲染中声像宽度越宽。 The results show that the extraction methods with less extraction errors can achieve better sound quality in binaural rendering, while the extracted ambient components with weaker inter-channel cross correlation can acquire wider sound images.
39319 考虑多进制LDPC码的符号特性，以及对其残留错误和删除的分析，本文采用多进制LDPC码作为内码，相同Galois域下的高码率RS码作为外码来构造多进制乘积码;并提出了一种低复杂度的迭代译码方案，减少信息传输的各类错误。 Considering the symbol characteristic of non-binary LDPC code, this paper used the non-binary LDPC code as the inner code, the high rate RS code under the same Galois field as the outer code to construct the non-binary product code based on the analysis of the residual erasures and errors; and a novel iterative method for non-binary product code is proposed to further reduce the various errors in information transmission.
39320 在译码时，只对前一次迭代中译码失败的码字执行译码，并对译码正确码字所对应的比特初始概率信息进行修正，增强下一次迭代多进制LDPC译码符号先验信息的准确性， During the iterative decoding, only codewords that failed to decode in the previous iteration are performed decoding, and the corresponding bit probability of the corrected codeword is modified to enhance the prior information accuracy of symbol in non-binary LDPC decoding of next iteration.
39321 减少内码译码后的判决错误，从而充分利用外码的纠错能力。 Then, the decision error after inner decoding is decreased, and thereby the error correction capability of the outer code can be full exploited.
39322 仿真结果显示，多进制乘积码相较于二进制LDPC乘积码有较大的编码增益，并通过迭代进一步改善了性能，高效纠正了信道中的随机错误和突发删除。 Simulation results show that the proposed non-binary product code scheme had excellent coding gain compared with binary LDPC product code, the performance was further improved using iteration, and the random errors and long burst erasures were effectively corrected.
39323 对于包含2%突发删除的高斯信道，在误比特率为10-6时，迭代一次有0.4 dB左右的增益。 For AWGN channel with 2% erasures, 0.4 dB gain can be obtained through iteration when the bit error rate is 10-6.
39324 针对目前车牌识别领域中，雾霾环境下车牌检测准确率低的问题，本文提出一种基于深度学习的抗雾霾车牌检测方法， Aiming at solving the problem of low license plate detection accuracy in the smog environment in the current license plate recognition field, a deep learning-based anti-smog license plate detection method is proposed in this paper.
39325 该方法能够检测民用车牌和机场民航车辆车牌。 The method can detect civil license plates and airport civil aviation vehicle license plates.
