Abstract:
ABSTRACT The current communication systems tend to use wireless broadband access technologies that provide many features to its subscribers, such as high speed data connectivity and good voice quality and video services for economical rates. WiMAX is one of the wireless broadband technologies, based on the standard IEEE 802.16 wireless metropolitan area network. The physical layer of WiMAX based on OFDM technique, in order to provide high data rates, minimize inter-symbol interference and fading effect. The designed system includes a data randomized module, error detection and correction module, mapping module that aid transmit more bits/symbol, pilot insertion and guard interval for estimation and reduce ISI, 256-point IFFT to generate OFDM symbols, long preamble for timing synchronization, and 64 cyclic prefix addition to combat the effect of fading channels. The complementary operations apply to the receiver blocks in reverse order. This paper presents a model for simulating and implementation of a complete WiMAX baseband system. First, the simulation was done using a Xilinx system generator incorporated with Simulink/Matlab and then it synthesized, implemented and verified as digital hardware using VHDL language and Xilinx ISE design suite with Spartan 3E XC320S1200 FPGA. Keywords:WiMAX, Physical Layer, OFDM, FPGA
