Public Types
typedef boost::shared_ptr< WirelessChannel >	WirelessChannelPtr
	Smart pointer that clients should use.
Public Member Functions
virtual double	getRecvdStrength (const WirelessCommSignal &signal, const PhysicalLayer &receiver) const
	Compute the signal strength at the receiver for the given signal.
virtual bool	signalHasError (double signalSinr, const WirelessCommSignal &signal) const
	Computes whether or not the signal has an error each time it is called based on some channel error model.
Static Public Member Functions

Member Function Documentation

WirelessChannelPtr WirelessChannel::create	(	PathLossPtr	pathLossModel,
		FadingPtr	fadingModel
	)			[inline, static]

A factory method to ensure that all objects are created via new since we are using smart pointers.

Parameters:

	pathLossModel	the path loss model that the channel will use.
	fadingModel	the fading model that the channel will use.

Definition at line 108 of file wireless_channel.hpp.

WirelessChannelPtr WirelessChannel::create

(

PathLossPtr

pathLossModel

)

[inline, static]

A factory method to ensure that all objects are created via new since we are using smart pointers.

Parameters:

pathLossModel

the path loss model that the channel will use.

Definition at line 101 of file wireless_channel.hpp.

References WirelessChannel().

double WirelessChannel::getRecvdStrength	(	const WirelessCommSignal &	signal,
		const PhysicalLayer &	receiver
	)			const [virtual]

Compute the signal strength at the receiver for the given signal.

Parameters:

	signal	the signal being transmitted.
	receiver	the physical layer object for which we will compute the received signal strength.

Returns:

the received signal strength value.

bool WirelessChannel::signalHasError	(	double	signalSinr,
		const WirelessCommSignal &	signal
	)			const [virtual]

Computes whether or not the signal has an error each time it is called based on some channel error model.

In general, a signal's error rate is based on its SINR, length, and data rate. The SINR is given as a parameter and the other two factors are included in the signal's packet.

Parameters:

	signalSinr	the current SINR of the signal.
	signal	the signal being tested, which includes the length and data rate of the signal's packet.

Returns:

true if an error occurs in the signal.
