simth::DeviceSystemIntf s,
const simth::PropertyList pl,
double  n = 0


virtual simthlib::AWGNChannel::~AWGNChannel  )  [inline, virtual]


Member Function Documentation

virtual void simthlib::AWGNChannel::getTransfer int  relative_time,
simth::FreqSignal trans
const [virtual]

Returns the channel transfer factors. This could be used for an ideal channel estimation. The result is written into the given simth::FreqSignal trans.

relative_time The relative time at which the transfer function is calculated, relative to the last time sample that was transmitted over this channel!
trans The simth::FreqSignal that receives the resulting transfer function.

Implements simthlib::Channel.

void simthlib::AWGNChannel::print std::ostream &  os  )  const [inline, virtual]

Reimplemented from simthlib::Channel.

void simthlib::AWGNChannel::transmit const simth::TimeSignal sym,
simth::TimeSignal outsym

transmits a symbol sequence over the channel

Implements simthlib::Channel.

propertylist_AWGNChannel not_a_function   )  [related]

These are the properties of class AWGNChannel . This list is auto-generated from the XML-Devicelist of this device by means of an XSLT transformation script.

Description of this device in the XML file: A channel with additive white gaussian noise and no further distortions.

Note that this class also has the Properties of its base classes. The direct base class is simthlib::Channel ; direct link to its propertylist should be propertylist_Channel(). The list below usually includes the properties that have been inherited from the base classes; the properties which belong only to this class can be found at the end of this list.

<sequencelength>, default "-1" -- The length of the input sequence. '-1' means it will be determined dynamically at runtime.

<string>, default "" -- Name of the SNR loop variable in your simulation setup

<string>, default "" -- Name of the channel refresh loop variable in your simulation setup

3 properties in this class. The above properties have been inherited from the base class simthlib::Channel .

<string>, default "awgn" -- The specific type of desired channel, i.e. the respective C++ class.

1 properties in this class.
