NRxAnts  Required  Positive scalar integer  Number of receive antennas 
MIMOCorrelation  Required  'Low' , 'Medium' , 'UplinkMedium' , 'High' , 'Custom'
 Correlation between UE and eNodeB antennas 'Low' correlation is equivalent
to no correlation between antennas.
'Medium' correlation level is applicable
to tests defined in TS 36.101 [2]
'UplinkMedium' correlation level
is applicable to tests defined in TS 36.104 [2].

NormalizeTxAnts  Optional  'On' (default), 'Off'
 Transmit antenna number normalization, specified as a
string. 'On' , lteFadingChannel normalizes
the model output by 1/sqrt(P) , where P is
the number of transmit antennas. Normalization by the number of transmit
antennas ensures that the output power per receive antenna is unaffected
by the number of transmit antennas.
'Off' , normalization is not performed.

DelayProfile  Required  'EPA' , 'EVA' , 'ETU' , 'Custom' , 'Off'
 Delay profile model. Setting DelayProfile to 'Off' switches
off fading completely and implements a static MIMO channel model.
In this case, the antenna geometry corresponds to the number of transmit
antennas (that is, the number of columns in the input in ),
the number of receive antennas, model.NRxAnts ,
and the MIMO correlation, model.MIMOCorrelation .
The temporal part of the model for each link between transmit and
receive antennas consists of a single path with zero delay and constant
unit gain. 
The following fields are required
or optional (as indicated) when DelayProfile is
set to a value other than 'Off' . 
DopplerFreq  Required  Scalar value  Maximum Doppler frequency, in Hertz. 
SamplingRate  Required  Numeric scalar  Input signal sampling rate, the rate of each sample in the rows
of the input matrix, in 
InitTime  Required  Numeric scalar  Fading process time offset, in seconds. 
NTerms  Optional  16 (default) scalar power of 2  Number of oscillators used in fading path modeling. 
ModelType  Optional  'GMEDS' (default), 'Dent'
 Rayleigh fading model type. 'GMEDS' , the Rayleigh fading is
modeled using the Generalized Method of Exact Doppler Spread (GMEDS),
as described in [4].
'Dent' , the Rayleigh fading is
modeled using the modified Jakes fading model described in [3].
Note:
ModelType = 'Dent' is
not recommended. Use ModelType = 'GMEDS' instead. 

NormalizePathGains  Optional  'On' (default), 'Off'
 Model output normalization. 'On' , the model output is normalized
such that the average power is unity.
'Off' , the average output power
is the sum of the powers of the taps of the delay profile.

InitPhase  Optional  'Random' (default), scalar value (in Radians),
or a numeric array  Phase initialization for the sinusoidal components of
the model, may be set as follows: the string 'Random' , the phases
are randomly initialized according to Seed . a scalar value, assumed to be in radians, is used
to initialize the phases of all components. an NbyLbyPbyNRxAnts numeric
array, used to explicitly initialize the phase in radians of each
component. In this case, N is the number of phase
initialization values per path, L is the number
of paths, P is the number of transmit antennas,
and NRxAnts is the number of receive antennas.
Note:
When ModelType is set to 'GMEDS' , N = 2 × NTerms . When ModelType is set to 'Dent' , N = NTerms .


The following field is required
when DelayProfile is set to a value other than 'Off' and InitPhase is
set to 'Random' . 
Seed  Required  Scalar value  Random number generator seed. To use a random seed, set Seed to
zero. Note:
To produce distinct results, use Seed values
in the range $$\mathrm{0...}{\text{2}}^{\text{31}}\u2013\text{1}\u2013\text{}({\scriptscriptstyle \frac{K(K\u2013\text{1})}{2}})$$ Where K = P × model.NRxAnts , the product of the number
of transmit and receive antennas. Seed values outside
of this recommended range should be avoided as they may result in
random sequences that repeat results produced using Seed values inside
the recommended range. 

The following fields are required
when DelayProfile is set to 'Custom' . 
AveragePathGaindB  Required  Vector  Average gains of the discrete paths, expressed in dB. 
PathDelays  Required  Vector  Delays of the discrete paths, expressed in seconds. This
vector must have the same size as AveragePathGaindB . 
The following fields are required
when MIMOCorrelation is set to 'Custom' . 
TxCorrelationMatrix  Required  Matrix  Correlation between each of the transmit antennas, specified
as a PbyP complex matrix. 
RxCorrelationMatrix  Required  Matrix  Correlation between each of the receive antennas, specified
as a complex matrix of size NRxAnts byNRxAnts .
