Characteristic information about TGn, TGah, TGac, and TGax multipath fading channels
Return the characteristic information of a TGah channel.
Create the TGah channel System Object. Specify a delay profile defined by the model E, path loss, 4 MHz of channel bandwidth and a 2x2 MIMO channel.
tgah = wlanTGahChannel; tgah.DelayProfile = 'Model-E'; tgah.LargeScaleFadingEffect = 'Pathloss'; tgah.ChannelBandwidth = 'CBW4'; tgah.NumTransmitAntennas = 2; tgah.NumReceiveAntennas = 2;
Return the delay by the channel filtering, the delay and average gain of each discrete path, and the path loss.
S = info(tgah)
S = struct with fields: ChannelFilterDelay: 7 ChannelFilterCoefficients: [18x17 double] PathDelays: [0 1.0000e-08 2.0000e-08 3.0000e-08 ... ] AveragePathGains: [-2.5000 -3.0000 -3.5000 -3.9000 0 ... ] Pathloss: 41.2126
S— Characteristic information about the channel
Characteristic information about the channel, returned as a structure containing the following fields:
ChannelFilterDelay: Channel filter delay
introduced by the implementation, measured in number of
fractional delay filter coefficients.
PathDelays: Multipath delay of the discrete
paths, measured in seconds.
AveragePathGains: Average gains of the
discrete paths, measured in decibels (dB).
Pathloss: Path loss between the transmitter
and receiver, measured in dB.
