Ieee80211DimensionalTransmitter

compound module

This transmitter model produces IEEE 802.11 transmissions that have dimensional transmission power (that changes over time and/or frequency) in their analog representation. The bit domain, symbol domain, and sample domains of the transmissions are not represented.

Some example values for the frequencyGains parameter:

default (flat signal): "left s 0dB either e 0dB right"
802.11a/g/n/ac OFDM spectral mask (for 20/40/80/160MHz bandwidth): "left c-b*1.5 -40dB linear c-b -28dB linear c-b*0.5-1MHz -20dB linear c-b*0.5+1MHz 0dB linear c+b*0.5-1MHz 0dB linear c+b*0.5+1MHz -20dB linear c+b -28dB linear c+b*1.5 -40dB right"

Extends

Name	Type	Description
DimensionalTransmitterBase	compound module	This transmitter model produces transmissions that use dimensional transmission power (that changes over time and/or frequency) in their analog representation and the configured modulation.

Parameters

Name	Type	Default value	Description
preambleDuration	double		preamble duration
headerLength	int		number of header bits added to the length of the MAC frame
bitrate	double		the bitrate of the transmitter is used to compute the duration of the transmission
power	double		transmission power
centerFrequency	double		center frequency of the band where the transmitter transmits on the medium
bandwidth	double		bandwidth of the band where the transmitter transmits on the medium
codeRate	double	1
modulation	string	"BPSK"	"BPSK", "16-QAM", "256-QAM"
gainFunctionCacheLimit	int	0	limits the number of gain functions cached for a given duration, centerFrequency and bandwidth
