OFDM Modulator and Demodulator
OFDM Modulator and Demodulator IPs are used for many broadband communication applications. The main application area is WLAN where the latest technology is referred as Wi-Fi 6 based on IEEE802.11ax. Also the IP cores are designed to be compatible with legacy WLAN standards. The cores include mainly FFT/IFFT and cyclic prefix insertion/removal blocks. Moreover, on the reciever side, there are also channel estimation, phase error estimation and equalization blocks in order to mitigate channel impairments.
- Compliant with IEEE 802.11a/b/g/n/ad/ax (also it can be extended to be compatible with 5G NR)
- Support for 64 to 4096 FFT points
- Support for 16-72 CP length
- Variable subcarrier spacing
