Digital Up Converter for Wimax System
In the recent times, mobile communication needs not only a high data rate transmission but also a relatively fast mobility. The mobile WiMAX based on Orthogonal Frequency Division Multiple Access (OFDMA) can addresses both of these requirements. To implement the mobile WiMAX (IEEE 802.16e) system, one must address a number of key issues in signal processing related to physical layer implementation. Within wireless base station system design, one continues to seek ways to add value and performance while increasing differentiation. In this paper solution is proposed mainly for the front end, in term of design of Digital Up Converter (DUC) which will obey the spectral consideration of WiMAX system (IEEE 802.16).
