TDD Wireless Broadband Communication System of Analysis
In wireless broadband communications in the development process,the user rapidly increasing volume of business,users are covered by the requirements and the limited spectrum resources available to the user the contradiction between the increasingly prominent.Users are eager to improve the system spectral efficiency in order to provide greater capacity,TDD duplex mode to resolve this contradiction is one of the core technologies.In this paper start with TDD principles,combined with the practical application of the complexity,the use of cost and other factors,highlighting the TDD in the McWiLL system applications,and a detailed analysis of its advantages and problems.Finally for the domestic wireless access developments and concluded that in the upcoming next-generation mobile communication systems,TDD will be widely used and play an important role.
