Design of Background Noise Suppression Circuit for Mobile Phones  [PDF]
Peng Luo
Journal of Computer and Communications (JCC) , 2016, DOI: 10.4236/jcc.2016.49003
Abstract: With the purpose of reducing the influence of background noise on the call quality of mobile phones, background noise suppression circuit is designed based on the principle of self-adaptive noise cancellation. Because this method is not involved in the nature of the noise itself, it can be used both for stationary noise cancellation and quasi-stationary noise cancellation. The working principle and circuit design of the system are introduced in detail. Simulated experiment was conducted in the lab, and its experimental results were analyzed. The experimental results show that the circuit works well with low cost, and has a broad prospect of application and popularization.
Another Important Parameter’s Research on Estimating Self-Similarity  [PDF]
Peng Luo, Juan Wang
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2016, DOI: 10.4236/ijcns.2016.98030
Abstract: It is convincingly demonstrated by numerous studies that the self-similarity of modern multimedia network traffic is presented by Hurst parameter (H). The specific performance is that the similar degree is higher along with the increase of H when H is between 0.5 and 1. However, it is doubtable that whether the complicated process of self-similarity can be described comprehensively by the parameter H only. Therefore, another important parameter cf has been proposed based on the discrete wavelet decomposition in this paper. The significance of the parameters is provided and the performance of the self-similarity process is described better.
Analysis of Cultural Differences between West and East in International Business Negotiation
Peng Luo
International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v3n11p103
Abstract: Economic globalization brings increasing communication of economy and trading among countries, and the negotiation has been the important part of international business activity in this process. The international business negotiation is not only the communication and cooperation in the economic domain, but the communication of culture among various countries. In the process of negotiation, negotiants’ idea and behavior are controlled by their own national cultures. There are large differences in thinking pattern, value view, group consciousness, negotiation style, benefit consciousness and law consciousness between western and eastern cultures, and these differences largely influence the process and result of negotiation and they are important factors we should consider in the negotiation.
Analysis of American Potential Benefits At the Back of “Considerable” Sino-American Trade Deficit
Peng Luo
International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v3n12p25
Abstract: The paper investigates reasons why there are large gaps in foreign trade statistics between China and America. Different statistic calibers, neglect of transit trade and transit added value, processing trade and industry transference, American increased direct investments in China, American multinational companies’ operation in China and the adoption of export control policy to China have done great deal in this. Through analysis, finally we find that US has obtained great benefits at the back of trade deficits. It has become a powerful weapon to open Chinese market.

Abstract: In this paper, we study the uniqueness and existence of solutions of RGSDEs with nonlinear resistance under an integral-Lipschitz condition of coefficients. Moreover we obtain the comparison theorem for RGSDEs with nonlinear resistance.
Qiong-peng Luo
Taiwan Journal of Linguistics , 2011,
Abstract: This study addresses two outstanding puzzles about the two well-known quantifiers mei and dou in Chinese: (i) the indefinite/definite asymmetry when mei leads the subject NP: dou is not needed when there is an indefinite or a reflexive object within the scope of mei and (ii) the subject/object asymmetry: when mei leads the subject NP, its distribution is restricted, depending on the type of the objects, and, by contrast, when it leads the object NP, its distribution is much freer. We propose a novel account for these puzzles. We argue that (i) the indefinite/definite asymmetry can be explained away if we assume that mei is a distributive quantifier with a portmanteau semantic structure, i.e., that it is a standard universal quantifier plus a matching function; (ii) mei can be domain-shifted into a distributive determiner to satisfy interpretability, and this explains the subject/object asymmetry and (iii) this domain-shifting is regulated by the Principle of Economy (cf. Reinhart (2006)), which is a last resort to satisfy interpretability
Problems in Development of Electrical Power in Rural China
Peng Gao,Guoliang Luo
Asian Social Science , 2009, DOI: 10.5539/ass.v5n12p27
Abstract: With development of electric power in rural China for several decades, it has attained great achievements. However, under the circumstance when urban and rural development is balanced in China, problems in development of electric power in rural China seem more prominent, mainly characterized by disbalance of development structure, lagging of macro-management and policy, and lack of vitality in electric power corporations in rural China.
BSDEs on finite and infinite horizon with time-delayed generators
Peng Luo,Ludovic Tangpi
Mathematics , 2015,
Abstract: We consider a backward stochastic differential equation with a generator that can be subjected to delay, in the sense that its current value depends on the weighted past values of the solutions, for instance a distorted recent average. Existence and uniqueness results are provided in the case of possibly infinite time horizon for equations with, and without reflection. Furthermore, we show that when the delay vanishes, the solutions of the delayed equations converge to the solution of the equation without delay. We argue that these equations are naturally linked to forward backward systems, and we exemplify a situation where this observation allows to derive results for quadratic delayed equations with non-bounded terminal conditions in multi-dimension.
Stochastic differential equations driven by G-Brownian motion and ordinary differential equations
Peng Luo,Falei Wang
Mathematics , 2013,
Abstract: In this paper, we show that the integration of a stochastic differential equations driven by G-Brownian motion in R can be reduced to the integration of an ordinary differential equations parametrized by a variable in ({\Omega},F). We study the sample solutions of G-SDEs by an extention of G-It\^o formula. And then we also get a comparison theorem for G-SDEs and its applications.
Solvability of coupled FBSDEs with quadratic and superquadratic growth
Peng Luo,Ludovic Tangpi
Mathematics , 2015,
Abstract: We derive two existence and uniqueness results for multi-dimensional and coupled systems of forward-backward SDEs when the generator of the backward equation may have quadratic growth in the control variable and the parameters of the forward equation are Lipschitz continuous. In the Markovian setting, we show existence and uniqueness in the superquadratic case for unbounded terminal conditions. This result extends to the non-Markovian case under a boundedness condition on the Malliavin derivative of the terminal condition and the generator. Furthermore, this condition can be dropped if the generator can be separated into a quadratic and a subquadratic part, and the terminal condition bounded. In this case the solution exists on a small time interval.
