Abstract: “The growth of 802.11-based wireless LANs provides higher data rates and greater system capacities. Among the IEEE 802.11 standards, the 802.11a standard based on OFDM modulation scheme has been defined for high-speed and large-system-capacity challenges. The paper firstly introduces WLAN and compares different WLAN standards. It presents the design of data scrambler and convolutional encoder for WLAN 802.11a transmitter, it also presents the synthesis and simulation results for the same using Xilinx CPLD XA9536XL-15-VQ44.”

Keywords: WLAN; OFDM; VHDL.
