| 1 | Cross-correlation function based multipath mitigation technique for cosine-BOC signals显示文摘We propose a new multipath mitigation technique based on cross-correlation function for the new cosine phased binary offset carrier(cosine-BOC) modulated signals, which will most likely be employed in both European Galileo system and Chinese Compass system. This technique is implemented to create an optimum cross-correlation function via designing the modulated symbols of the local signal. And the structure of the code tracking loop for cosine-BOC signals is quite simple including only two real correlators. Results demonstrate that the technique efficiently eliminates the ranging errors in the medium and long multipath regions with respect to the conventional receiver correlation techniques. | Huihua Chen Weimin Jia Minli Yao | 2013 | Journal of Systems Engineering and Electronics2013，24，5： | 3 |
| 2 | 2-D DIRECTION FINDING OF COHERENT SIGNALS VIA TEMPORO-SPATIAL PROCESSING显示文摘In most wireless communication systems, two-dimensional Directions-Of-Arrival (DOA) of multipath signals need to be found for spatial selective transmission. However, it is quite difficult to find their DOAs due to the coherent nature of multipath signals and considerable computations when performing 2-D searches. In this paper, a new algorithm to estimate 2-D DOA of multiple narrow-band signals is proposed. A DOA cyclic matrix is constructed whose eigenvalues and eigenvectors can be simultaneously used to extract 2-D DOA without 2-D searches. By exploiting the temporal property of cyclostationarity, the signal detection capability is significantly improved. Besides, based on the decorrelation model for mobile terminal signals, the algorithm can be effectively extended to the coherent case without spatial smoothing and the loss of array aperture. Simulation results are given to illustrate the performance of the new algorithm. | Jin Liang (PLA Information Engineering College, 1001 P. O.

| 8 | Variable partial-update NLMS algorithms with data-selective updating显示文摘We note that some existing algorithms are based on the normalized least-mean square(NLMS)algorithm and aim to reduce the computational complexity of NLMS all inherited from the solution of the same optimization problem,but with different constraints.A new constraint is analyzed to substitute an extra searching technique in the set-membership partial-update NLMS algorithm(SM-PU-NLMS)which aims to get a variable number of updating coefficients for a further reduction of computational complexity.We get a closed form expression of the new constraint without extra searching technique to generate a novel set-membership variable-partial-update NLMS(SM-VPU-NLMS)algorithm.Note that the SM-VPU-NLMS algorithm obtains a faster convergence and a smaller mean-squared error(MSE)than the existing SM-PU-NLMS.It is pointed out that the closed form expression can also be applied to the conventional variable-step-size partial-update NLMS(VSS-PU-NLMS)algorithm.The novel variable-step-size variable-partial-update NLMS(VSS-VPU-NLMS)algorithm is also verified to get a further computational complexity reduction.Simulation results verify that our analysis is reasonable and effective. | ZHU FengChao GAO FeiFei YAO MinLi ZOU HongXing | 2014 | Science China(Information Sciences)2014，57，4： | 0 |

| 10 | EVA2.0:Investigating Open-domain Chinese Dialogue Systems with Large-scale Pre-training显示文摘Large-scale pre-training has shown remarkable performance in building open-domain dialogue systems.However,previous works mainly focus on showing and evaluating the conversational performance of the released dialogue model,ignoring the discussion of some key factors towards a powerful human-like chatbot,especially in Chinese scenarios.In this paper,we conduct extensive experiments to investigate these under-explored factors,including data quality control,model architecture designs,training approaches,and decoding strategies.We propose EVA2.0,a large-scale pre-trained open-domain Chinese dialogue model with 2.8 billion parameters,and will make our models and codes publicly available.Automatic and human evaluations show that EVA2.0 significantly outperforms other open-source counterparts.We also discuss the limitations of this work by presenting some failure cases and pose some future research directions on large-scale Chinese open-domain dialogue systems. | Yuxian Gu Jiaxin Wen Hao Sun Yi Song Pei Ke Chujie Zheng Zheng Zhang Jianzhu Yao Lei Liu Xiaoyan Zhu Minlie Huang | 2023 | Machine Intelligence Research2023，20，2： | 0 |
