Architecture design framework for flexible and configurable WiMAX OFDMA baseband transceiver

This paper describes a design framework for VLSI architecture design of WiMAX OFDMA Baseband Transceiver (Physical layer - PHY). Architecture design is emphasized on a balance of flexibility and implementation efficiency, in term of optimum area usage and data processing speed. Flexibility feature of proposed architecture is obtained by employing some design approaches, such as performing design partitioning to maintain design modularity, providing software access for configuration, and designing control unit. The design has successfully implemented in 0.13 μm CMOS technology. Implementation result shows that chip area is about 13.4 mm². The implemented design can deliver throughput up to 41 Mbps.
