Member Function Documentation

◆ GetChannel()

virtual Ptr<const ChannelMatrix> ns3::MatrixBasedChannelModel::GetChannel	(	Ptr< const MobilityModel >	aMob,
		Ptr< const MobilityModel >	bMob,
		Ptr< const PhasedArrayModel >	aAntenna,
		Ptr< const PhasedArrayModel >	bAntenna
	)

pure virtual

Returns a matrix with a realization of the channel between the nodes with mobility objects passed as input parameters.

We assume channel reciprocity between each node pair (i.e., H_ab = H_ba^T), therefore GetChannel (a, b) and GetChannel (b, a) will return the same ChannelMatrix object. To understand if the channel matrix corresponds to H_ab or H_ba, we provide the method ChannelMatrix::IsReverse. For instance, if the channel matrix corresponds to H_ab, a call to IsReverse (idA, idB) will return false, conversely, IsReverse (idB, idA) will return true.

Parameters

aMob	mobility model of the a device
bMob	mobility model of the b device
aAntenna	antenna of the a device
bAntenna	antenna of the b device

Returns: the channel matrix

Implemented in ns3::ThreeGppChannelModel.

◆ GetKey()

static uint64_t ns3::MatrixBasedChannelModel::GetKey	(	uint32_t	a,
		uint32_t	b
	)

inlinestatic

Generate a unique value for the pair of unsigned integer of 32 bits, where the order does not matter, i.e., the same value will be returned for (a,b) and (b,a).
