The explosive growth of 802.11-based wireless LANs has attracted
interest in providing 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 to address high - speed and large-system-capacity challenges.
Hardware implementations are often used to meet the high-data rate requirements
of 802.11a standard. Although software based solutions are more attractive due
to the lower cost, shorter development time , and higher flexibility , it is
still a challenge to meet the high-data-rate requirements of 802.11a by
software. Software - based 802.11a digital baseband transmitter can be designed
using Verilog HDL /Matlab.Digital signal processors (DSPs) are a special class
of processor optimized for signal-processing applications in communication
systems.
