A scalable orthogonal frequency-division multiple access (OFDMA) engine for mobile worldwide interoperability for microwave access (WiMAX) can be used to accelerate the development of mobile broadband wireless networks based on the IEEE 802.16 standard.
Scalable OFDMA is a key technology behind mobile WiMAX and is widely regarded as an enabling technology for future broadband wireless protocols including the 3GPP and 3GPP2 long term evolution standards.
The scalable OFDMA engine should possess the following features:
- Support for 128, 512, 1K, and 2K FFT sizes to address variable bandwidths from 1.25 to 20 MHz
- Support for both downlink partial usage of subchannels (PUSC) and full usage of subchannels (FUSC) and uplink PUSC mandatory schemes
- Support for both fixed and variable pilots and runtime configurable cyclic prefix insertion
- Highly parameterizable design
- Optimized for efficient use of FPGA device resources
