wlanHEDemodulate
Syntax
Description
recovers a demodulated frequency-domain signal by orthogonal frequency-division
multiplexing (OFDM) demodulating received high-efficiency (HE) time-domain signal
sym
= wlanHEDemodulate(rx
,field
,cfg
)rx
. The function demodulates rx
by using HE
transmission parameters cfg
and signal field value
field
.
specifies channel bandwidth sym
= wlanHEDemodulate(rx
,field
,cbw
,hegi
,ru
)cbw
, guard interval
hegi
, and resource unit determined by the size and index specified
in ru
. If ru
is not specified, the function
returns the demodulated signal assuming a full band configuration. To demodulate the
HE-Data field when the PHY format is unknown, use this syntax.
