We start from VSA software development. There are 4 packet types defined in the IEEE 802.11ax specification and listed in the table 1. Different packet formats will be used according to different usage scenarios. Let's take HE SU PPDU Packet format as an example. In the s/w development, we refer to the specification and generate each field (table 2) of the packet with different bandwidth, modulation and coding schemes (MCS) and number of spatial streams. The available settings are listed in Table 3. The generated complex IQ waveform will be verified by the commercial VSA software (Keysight 89600) to ensure that the waveform is correctly generated and the SIGNAL information can be decoded.
