In this section, the rapid prototype methodology presented in the previous section is applied to the design of an IEEE 802.11a baseband radio. Briefly, IEEE 802.11a is a standard for WLAN radios in the 5GHz unlicensed band [1]. The standard based on OFDM (Orthogonal Frequency Division Multiplexing) uses 48 data subcarriers in a 20 MHz bandwidth to support data rates of 6 to 54 Mbps. The topic of OFDM and the IEEE 802.11a standard is covered in detail in earlier chapters. Following the rapid prototype design flow of Figure 8.1, the fixed-point design for the baseband radio is done in HDS based on the floating-point model and simulation in MATLAB. Once the HDS design is verified, VHDL is generated for each design ...
