wlanPacketDetect
Estimate timing offset of OFDM packet
Syntax
Description
estimates the timing offset between the start of
received signal startOffset
= wlanPacketDetect(rxSig
,cbw
)rxSig
and the
start of the detected preamble for channel
bandwidth cbw
. For more
information, see Packet Detection Processing.
Note
This function supports packet detection of OFDM modulated signals only.
specifies the sample at which the function begins
autocorrelation processing relative to the start
of the received signal.startOffset
= wlanPacketDetect(rxSig
,cbw
,offset
)
specifies the threshold that the decision
statistic must meet or exceed to detect a packet. startOffset
= wlanPacketDetect(rxSig
,cbw
,offset
,threshold
)
[
also returns the decision statistics of the packet
detection algorithm for any of the input argument
combinations in previous syntaxes.startOffset
