Short Name: FEC Coding Type
Property of niWLANAnalysis
Specifies the type of forward error correction (FEC) coding used if you set the OFDM Non-HT Modulation Mode property to OFF, and the Standard property to 80211N MIMOOFDM, 80211AC MIMOOFDM, 80211AF MIMOOFDM, or 80211AX MIMOOFDM as defined in section 20.3.11.3 of the IEEE Standard 802.11n-2009, section 22.3.10.5 of the IEEE Standard 802.11ac-2013, section 23.3.10.5 of the IEEE Standard 802.11af-2013 and section 27.3.11.5 of IEEE P802.11ax/D6.0.
The toolkit ignores this property if you set the OFDM Header Detection Enabled property to True for PPDU types other than Trigger-Based PPDU.
The toolkit uses the value of this property to decode bits that are obtained after OFDM demodulation.
You must use the following active channel string formats to configure this property.
| Standard Property Value | PPDU Type | Active Channel String Syntax |
|---|---|---|
| 80211N MIMOOFDM, 80211AF MIMOOFDM | — | "" (empty string) |
| 80211AC MIMOOFDM | SU PPDU | "" (empty string) |
| MU PPDU | "userx" | |
| 80211AX MIMOOFDM | SU PPDU, Extended Range SU PPDU | "" (empty string) |
| MU PPDU, Trigger-Based PPDU | "userx" |
The default value is BCC.
| BCC (0) |
Specifies that the FEC coding type is binary convolutional code (BCC). |
| LDPC (1) |
Specifies that the FEC coding type is low-density parity check (LDPC). |
