Constructor & Destructor Documentation

◆ UnderwaterHMMPhysical()

UnderwaterHMMPhysical::UnderwaterHMMPhysical ( )

Constructor of UnderwaterHMMPhysical class.

◆ ~UnderwaterHMMPhysical()

UnderwaterHMMPhysical::~UnderwaterHMMPhysical ( )
virtual

Destructor of UnderwaterHMMPhysical class.

Member Function Documentation

◆ ber2per()

double UnderwaterHMMPhysical::ber2per ( double  ber,
Packet *  p 
)
protectedvirtual

Returns the packet error rate by using the BER from HMM and the size of a packet

Parameters
beraccording to HMM state
pPacket
Returns
PER of the packet.

Referenced by endRx().

◆ command()

int UnderwaterHMMPhysical::command ( int  argc,
const char *const *  argv 
)
virtual

TCL command interpreter. It implements the following OTcl methods:

Parameters
argcNumber of arguments in argv.
argvArray of strings which are the command parameters (Note that argv[0] is the name of the object).
Returns
TCL_OK or TCL_ERROR whether the command has been dispatched successfully or not.

Reimplemented from UnderwaterPhysical.

◆ endRx()

void UnderwaterHMMPhysical::endRx ( Packet *  p)
overrideprotectedvirtual

Handles the end of a packet reception

Parameters
Packet*p Pointer to the packet received
