getNumPostFECPaddingBits
Description
Examples
Calculate Number of Post-FEC Padding Bits for HE Transmissions
This example shows how to calculate the required number of post-forward-error-correction (post-FEC) padding bits for high-efficiency (HE) WLAN transmissions.
Calculate Number of Post-FEC Padding Bits for HE SU Transmission
Parameterize an HE single-user (HE SU) transmission by creating a wlanHESUConfig
object.
cfgHESU = wlanHESUConfig('ChannelBandwidth','CBW80','MCS',7);
Calculate the number of post-FEC padding bits required for waveform generation.
n = getNumPostFECPaddingBits(cfgHESU)
n = 3000
Calculate Number of Post-FEC Padding Bits for HE MU Transmission
Parameterize an HE multi-user (HE MU) transmission by creating a wlanHEMUConfig
object.
cfgHEMU = wlanHEMUConfig(40);
Calculate the number of post-FEC padding bits required for waveform generation.
n = getNumPostFECPaddingBits(cfgHEMU)
n = 1×5

Calculate Number of Post-FEC Padding Bits for HE TB Transmission
Parameterize an HE trigger-based (HE TB) transmission by creating a wlanHETBConfig
object.
cfgHETB = wlanHETBConfig('ChannelBandwidth','CBW40','MCS',6, ... 'NumTransmitAntennas',4,'PreFECPaddingFactor',3);
Calculate the number of post-FEC padding bits required for waveform generation.
n = getNumPostFECPaddingBits(cfgHETB)
n = 324
Input Arguments
cfg
— HE transmission parameters
wlanHEMUConfig
object | wlanHESUConfig
object | wlanHETBConfig
object
HE transmission parameters specified as one of these objects.
wlanHEMUConfig
— HE MU transmissionwlanHESUConfig
— HE SU transmissionwlanHETBConfig
— HE TB transmission
Output Arguments
n
— Required number of post-FEC padding bits
binary-valued scalar | binary-valued column vector
Required number of post-FEC padding bits, returned as one of these values.
A binary-valued scalar for single-user transmissions
A binary-valued column vector of length Nusers for multi-user transmissions, where Nusers is the number of users in the transmission. In this case, the kth entry is the required number of post-FEC padding bits for the kth user in the transmission.
