Notes

1. This model can be used to form PPDU frame, according to IEEE 802.11a standard.

2. Fig.1 shows a block diagram of the IEEE 802.11a baseband transmitter. One sample overlap occurs between preamble and SIGNAL field as well as between SIGNAL field and DATA field. The number of OFDM symbols during DATA field is determined by the three parameters, Modulation, Coding, and Length.. For some details, please refer to the PAD11A model.
