Research On Key Techniques Of Radio Resource Allocation In Relay-enhanced Cellular Networks

With the integration of triple-play develops into the substantial propulsion phase in China, the market demand of the terminal equipments, as the supporting body of the integration of triple-play, is rising rapidly. In recent years, the integrate tendency of the terminal(STB) industry is obviously. When the concentration ratio of the industry continues improve, the competition between those leading enterprises is constantly deepening as well. The terminal enterprises in China promote to adjust product construction, optimize and upgrade for better performance, by researching and developing the new production constantly in the market which competes increasing fiercely. Then those enterprises will enhance the overall competitiveness and profitability further in the market for sustainable developing. The manufacture of new products face more risk, so the benefit evaluation and risk analysis of the new product investment projects is not only the necessary steps and methods of the scientification of decision-making on investment, but also an important guarantee of the terminal enterprises to keep sustainable development and reduce the subjectivity and blindness during the process that makes the project investment decision.This document analysis and estimate the benefit and risk of this project, the WG project in JZ company, by uses a combination method which includes demonstration and standard, as well as qualitative and quantitative analysis, through the cost and benefit, the micro and macro double angle, analyzing the uncertainty and the risk of the investment, making the theory be closely associated with practice. This document introduces the present situation of the enterprise and the project from an investor’s perspective with the theory of the economic and the project management, analyzes the market requirement of the products in this project, gives a reasonable prediction for the target market and the price. According to the benefit evaluation, selecting the benefit evaluation parameters, on the basis of drawing up the benefit evaluation time, the product price and the cost, we estimate the income and the cost, calculate the main indicators of financial benefit such as the financial internal rate of return, the financial net present value, the investment recovery period, the balance point of profit and loss and the rate of return on investment, etc., which compare with the prescriptive financial indicators to further distinguish the financial viability of the proposed project. Through analyzing the main several risk factors which include the financial risk, the technology risk, the market risk and the operation risk, then the risk prevention measures were proposed. At last, the analysis conclusion of the benefit evaluation and the risk analysis will be as an important gist for the investment projects.
