PHY Features
• IEEE 802.11n draft 2.0 MIMO OFDM
- 1 transmitter and 2 receivers (1T2R).
- 20MHz and 40MHz bandwidth transmission.
- Short Guard Interval (400ns).
- 1 spatial stream STBC transmission for extended coverage.
- Sounding packet.
• DSSS with DBPSK and DQPSK, CCK modulations with long and short preamble.
• OFDM with BPSK, QPSK, 16QAM, 64QAM, and 256QAM modulations. Convolutional coding rate:
1/2, 2/3, 3/4, and 5/6.
• Maximum data rate 54Mbps in 802.11g and 300Mbps in 802.11n.
• OFDM receive diversity with MRC using up to 4 receive paths. Switch diversity used for DSSS/CCK.
• Hardware antenna diversity.
• Selectable digital transmit and receiver FIR filters
• Programmable scaling in transmitter and receiver to trade quantization noise against increasing
probability of clipping.
• Fast receiver automatic gain control (AGC).
